    GLWorldScene also takes note of empty molecule.
    
    - this is for the case when a molecule is signalled empty before it signals
      ready for removal. This may happen cause the empty and the removal signal
      come from different sources, empty from GLMoleculeObject_molecule and
      removal from the board.

    FIX: QtObservedAtom's AtomMoleculeIndex was not informed of molecule index changes.
    
    - hence, we return the QtObservedMolecule of the molecule to which the atom is
      associated. And this reference is updated whenever the associated molecule
      changes.
    - getAtomMoleculeIndex() -> getAtomMolecule().
    - signal renamed moleculeIndexChanged -> moleculeChanged.

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Sat Feb 13 16:43:33 2016 +0100

    GLWorldScene RemovedMolecules now uses QtObservedMolecule* as key.
    
    - moleculeId_t is not unique, a new molecule of the same id might have already
      been instantiated. The shared_ptrs live till the end, hence the memory
      address can be safely used as unique key to the respective molecule instance.
    - signatures of signal removeMolecule() and slots moleculeRemoved() and
      moleculeEmptied() changed from id to this ptr.

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Sat Feb 13 16:30:05 2016 +0100

    FIX: GLWorldScene's moleculesAtomRemoved was checking QtObservedAtomMap.
    
    - however, the atom may already be a different one. Also, we do not even need
      it as we obtain the molecule from QtObservedMolecule directly.
    - also, molecule may no longer be present in MoleculesInSceneMap but still in
      RemovedMolecules and no molecule with same id already instantiated ...

Date:   Sat Feb 13 15:50:41 2016 +0100

    SignedOn_t in QtObservedInstanceBoard is again just a set.
    
    - we do not need multiple entries for molecule anymore.

    Removed last...removed in QtObservedInstanceBoard.
    
    - this does not do anything useful anymore, we may just pass the id we obtained
      from ObservedValuesContainer as Qt signal.

    TEMP: Decreased waiting times in QtGUI's test mode.

commit 178c147450531d80569a189fe4c34af69de4e4a5
Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Wed Jan 27 22:29:01 2016 +0100

    AtomInserted/Removed of QtObservedMolecule sends ptr as unique key.
    
    - this is used to associate the atom with the right molecule. This is needed in
      case when the molecule is deleted and a new one with the same id is created.
      If signals are delayed, we need to know which atomInserted/Removed signal to
      associated with which GLMoleculeObject_molecule.

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Wed Jan 27 22:24:07 2016 +0100

    GLWorldScene places GLMoleculeObject_molecule into extra list before removal.
    
    - GLMoleculeObject_molecule sends signal when no atoms are left.
    - GLMoleculeObject_molecule is destroyed when signal is obtained and we have
      placed it in removal list before.

    Removed RefCounted... again.

commit b9c95d65f97a99999c0747693845e4399ce64509
Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Wed Jan 6 09:36:58 2016 +0100

    All ..Inserted/..Removed signals now go through GLWorldScene.
    
    - this should enforce synchronicity of the signals. If we mix direct and
      queued connections, then this cannot be ensured.
    - the idea is that GLWorldScene gets all Inserted/Removed signals for atoms and
      molecules from the QtObservedInstanceBoard. It connects to each
      QtObservedMolecule and thus can call the GLMoleculeObject_molecule's
      atomInserted, atomRemoved functions in sequence.
    - removed RemovalMolecules, no longer needed.
    - we now enforce with mutexes that instantation of molecule and MissedStateMap
      do not interfere, i.e. it is always perfectly clear whether to push a signal
      into the Map or whether to call the function of the present GLMolObj_mol.
    - FIX: MoleculesInScene_mutex has not been used properly, now is.
    - DOCU: Updated construct qt-gu documentation with the new concept.

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Thu Jan 7 17:48:51 2016 +0100

    FIX: GLMoleculeObject_.. does not care whether selection state did not change.
    
    - maybe we just got the event too late and actually two changes occured in
      between.

commit 239282d0a3f78dfb3708317c784b5d231ecd4fbf
Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Thu Jan 7 13:00:38 2016 +0100

    FIX: Making sure that atomInserted is received from same source in GLWorldScene and GLMoleculeObject_molecule.
    
    - otherwise we cannot guarantee that the events are processed in order.

Author: Frederik Heber <heber@ins.uni-bonn.de>

    FIX: indexChanged from QtObserved... transmit both old and new id.

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Thu Jan 7 11:28:10 2016 +0100

    QtObserved... now count the subjectKilled() from the containes values.
    
    - we no longer loop this through the ObservedValuesContainer.
    - also initObservedValues() is not longer a static function but now used inside
      the QtObserved..'s cstor.

Date:   Wed Jan 6 18:34:22 2016 +0100

    QtObservedInstanceBoard now sends QtObserved..::ptr around in signals.
    
    - this should get rid of the problem that we need to keep the QtObservedAtom
      until it was requested at least once. And we don't know for how long. Now,
      we simply place the shared_ptr into the signal (to which it seems to be
      copied) and hence a representation of the atoms remains valid.
    - cstor of GLMoleculeObject_.. take Observed.. as ref.

    GLMoleculeObject_atom and .._molecule don't get QtObserved... right away.
    
    - needs to be checked for empty instance first.

    CHECK: tempcommit: Removed Cacheable of TesselationHull for GLMoleculeObject_molecule.
    
    - this may cause hiccups with the observed instances with the O/O system and
      makes no sense anyway as it gets updated all the time?

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Tue Jan 5 23:17:39 2016 +0100

    ObservedValuesContainer now asserts that observedinstance has been requested at least once before deletion.
    
    - this should prevent that the observed instance is instantiated and deleted
      before the signal has gotten through to the GUI.
    - get() returns NULL when not present.

commit f9ea954a9527c505fe36e310ee6f51bbade0055b
Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Wed Dec 30 19:42:38 2015 +0100

    FIX: ObservesValuesContainer uses internal struct for two iterators for observedvalues.
    
    - we need these two additional iterators (apart from the deque) in order to
      step through the created instances one-by-one as they are expected in this
      manner by the QtGUI which, though lacking behind, is trying to process all
      the seen events.

commit 0ce43805b209245ae6fcbc802c627f0d009497be
Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Wed Dec 30 15:28:53 2015 +0100

    FIX: ObservedValuesContainer uses deque for internal observed values.
    
    - it may happen that an atom is created before the _visual representation_
      got destroyed (and hence it's QtObserved... would be destroyed). In that
      case the QtObservedInstanceBoard fails with an assertion.
    - Now, we use a deque. At the front end, we have all the observedvalues that
      have not yet been deleted, on the back end we have the observedvalues to
      the currently active instance.
    - removed unused getRefCount().

Date:   Mon Dec 28 20:20:43 2015 +0100

    Removed QtSelectionChangedAgent.
    
    - it is no longer used. We either listen to molecule/atom's selection changes
      directly or to all of them via the respective relay, i.e. MoleculeObserver.

Date:   Mon Dec 28 20:14:32 2015 +0100

    Removed QtSelectionAgent usage in QtMoleculeListView.
    
    - instead we subscribe to MoleculeObserver directly.

    Removed QtSelectionUsage in GLWorldView and related.
    
    - instead GLMoleculeObject_.. directly use observedvalue to get notified when
      they have been (un)selected.

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Sun Dec 13 17:06:18 2015 +0100

    FIX: QtObservedInstanceBoard needs to allow delayed atomInserted from World.
    
    - we may get the notification from molecule before we get the insertion from
      the World. Hence, we store any ids obtained from molecule insertion if
      the set of the new atom's observed values have not been generated yet.

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Sun Dec 13 15:15:58 2015 +0100

    FIX: ObservedValue need to be removed with a bit of delay.
    
    - ObservedValue has higher priority than e.g. QtObservedAtom. Hence, will
      also receive subjectKilled() before QtObservedAtom does. But right after
      all of these are received(), ObservedValueContainer will remove the instance
      which drops the shared ptr's count to zero (because Observer/Observables
      do not store shared_ptr but only ptrs!) and its dstor is called. Therefore,
      QtObservedAtom cannot access the ObservedValue any longer and this is against
      how the design was meant to be (ObservedValue lives at least as long as
      respective side in Qt needs access to its information).

Date:   Mon Jan 25 15:15:23 2016 +0100

    QtObservedAtom, ..Molecule, and ObservedValue_wCallback have flag to indicate invalid callback.
    
    - due to Qt's signal/slot destruction, which follows no proper order,
      we need to invalidate callback when their owners are destroyed. Each has a
      note-function() that flips the boolean to show the callbacks invalidity.
    - TODO: So far this is not nice, especially w.r.t to ObservedValue_wCallback
      because of templatization. We cannot place them in a loop and this makes
      this very error-prone once more Values are added ...

    Equipped QtInfoBox with mutex and split clearTabs().
    
    - this avoids a memory corruption with signal/slots as the first atomRemoved()
      signal also removes the molecule and hence the QtObservedMolecule ptr who
      is the recipient of the subsequent moleculeRemoved() signal.

    All QtMoleculeItem now heed QtObservedMolecule and QtMoleculeList takes InstanceBoard.
    
    - QtMoleculeItems no longer use Observer/Observable but get updates via
      signal/slot from QtObservedMolecule.
    - QtMoleculeList listens to its molecule signals.

    ObservedValuesContainer now stores QtObserved.. instances directly.
    
    - we need this as QtObservedAtom and ..Molecule must signOn() to World's
      instance right away. If later requests to ObservedValuesContainer::get()
      cause new signOn()s, then these might fail.
    - we now work with QtObserved..::ptr directly everywhere.

Date:   Thu Oct 29 11:46:45 2015 +0100

    Extracted all ObservedValue functionality out of GLMoleculeObject_atom.
    
    - i.e. GLMoleculeObject_atom is reduced to simple displaying, updated via
      Qt signals. These signals are connected to a QtObservedAtom which in turn
      now contains all the ObservedValue functionality.
    - this is preparatory for having a single (Observed)Atom as representer of
      its associated World's atom in the QtGui part of the code.

    Extracted functions handling refcounting of ObservedValues into ObservedValuesContainer.
    
    - this avoids a lot of code duplication.

    Moved and renamed QtInstanceInformationBoard -> QtObservedInstanceBoard.
    
    - this is preparatory for adding ObservedAtom and ObservedMolecule classes
      that combine all observed information on either type.

    FIX: QtMoleculeItem not signing off after subjectKilled().

commit 9140be0febff13d22ce6bcb71d21138fddcd35bf
Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Sat Oct 17 17:42:17 2015 +0200

    Added QtInstanceInformationBoard that handles ObservedValues through the QtGui interface.
    
    - this is meant as a instantiator of all ObservedValue's needed by QtGui for
      representing information from the World. The ObservedValue's are instantiated
      separately w.r.t. to the instance for the visual representation. This is
      light-weight and can be performed in the same thread, while the visual
      representation's instantiation can be done elsewhere and there we just need
      to access the ready ObservedValue's that exist as long as they are needed
      by the QtGui.

commit f57e61aaf0b459993a691b4a9cff578b6345c375
Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Mon Jan 25 12:01:10 2016 +0100

    Changed GLMoleculeObject_...:countSubjectKilled() to taking id parameter.
    
    - this is a precursor for when the ObservedValues reside with
      QtInstanceInformationBoard.
    - enhanced ObservedValue_wCallback to take a bound getIndex function().
    - additionally, we route internally to ObservedValue::get() and this gets us
      out of the painful situation where we need to supply an index getter to the
      ObservedValue that monitors the index (and hence must be present already to
      bind to its get function).

    GLMoleculeObject_bond's ObservedValues is now all static.
    
    - again, the same change as with .._molecule and .._atom.

Date:   Sat Oct 17 14:55:30 2015 +0200

    GLMoleculeObject_atom's ObservedValues is now all static.
    
    - this is equivalent to the changes to GLMoleculeObject_molecule.

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Sat Oct 17 14:40:14 2015 +0200

    GLMoleculeObject_molecule's ObservedValues is now all static.
    
    - this is preparatory for extracting their instantation to an external class
      InstanceInformationBoard that keeps track of the lives of instances in the
      World that are needed inside QtGui (e.g. for visual representation).

Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Sat Oct 17 14:18:30 2015 +0200

    FIX: GLMoleculeObject_molecule::updateAtoms() used DisplayAtoms directly.
    
    - we need an old and a new set, i.e. the difference needs to be discernable
      between updates. However, so far we updated the old set directly, too.

    FIX: QtInfoBox only updatePage() when ref still present (no subjectKilled() yet).

commit 10bbe9b776c5a20167fd7cc820200b66ef1588c3
Author: Frederik Heber <heber@ins.uni-bonn.de>
Date:   Fri Oct 16 13:51:16 2015 +0200

    FIX: All ObservedValue's of GLMoleculeObject_atom/bond/molecule wrapped into vector.
    
    - the idea is that a GLMoleculeObject may only remove itself _after_ each and
      every contained Observer has gotten the subjectKilled() signal from the
      Observables. Only then will destroying the Object and its members thereby
      not cause any signOff() which try to access Observables or their channels
      which are no longer present. This can be imagined as a graph where we have
      to start destroying object at the very bottom.
    - This is the avoid the following conflict: A superior object gets note of
      a molecule to be removed. It sends the visual representation a signal to
      remove itself, which causes it to use signOff(). On a parallel track (in
      another thread) we have the observed object calling subjectKilled() to
      inform any Observer about its immediate destruction. These two tracks
      collide. Now, we let first pass all subjectKilled() and when the last
      Observable has gotten its signal, we begin destroying the visual rep.
    - rerouted signal/slots accordingly.

    FIX: GLMoleculeObject_molecule::subjectKilled() should not call deactivateObserver().
    
    - we just take note that we are signedOff.

Date:   Fri Oct 16 10:58:31 2015 +0200

    FIX: GLWorldScene has additional moleculePrepared... slots and signals.
    
    - i.e. we first insert into MoleculesInMap via direct connection and then
      signal is emitted (queued) to construct the actual GLMoleculeObject_molecule.

    FIX: GLMoleculeObject_molecule still contained hack to get upper bound on molecule's bounding box.
    
    - we don't longer need the hack as we have the molecule cleverly updating the
      box and an ObservedValue.

    Removed molecules_deprecated from World and unnecessary includes of MoleculeListClass and all insert/erase.
    
    - this goes along the lines of removing "remove me when we don't need
      MoleculeCistClass anymore".

    - AddHydrogenCorrection did never really worked and is dropped (was commented
      out in .._ToFiles anyway).

    FIX: molecule's BoundingBoxSweepingAxis used unordered set of atomids.
    
    - this needs to be an ordered set to prevent O(N) access on updating values.

    Molecule now has maps with old values for bond counts and element number per atom.
    
    - this allows to update the total bond count and the formula in an
      O(N log N) fashion.

    atom now uses associate... and disassociatedAtomWithMolecule().
    
    - this is used to gather all functions that need to be called when a new atom
      joins a molecule such as signing on to certain channels or updating certain
      internal values of the molecule.

    Extracted common code out of Molecule/AtomObserver into EntityObserver.

    - removed AtomObserverStub, does not work anymore with extracted
      EntityObserver.

    Added select() and unselect() functions to atom and molecule, also SelectionChanged channel.
    
    - this allows for more specific selection changs to be signalled.
    - this extends the current World's SelectionChanged channel that informs about
      selection changes by a more fine-grained/instance-specific change signalling.

    FIX: molecuilder.py is now loaded after GUI is done initializing.
    
    - otherwise consequences of loaded session (atoms, ...) are not displayed.
    - originally, this was done on purpose as it is quicker to just load stuff into
      the world and then tell the GUI to show what's there. However, now, due to
      constraints with different threads, this is no longer possible.

    Added recreateAtom() and recreateMolecule() to World.
    
    - in order to overcome problems with Qt signals being delayed so much that
      in between sending and receiving the id of a newly instantiated atom has
      changed, we need to set the right id (after undo/redo commands) right
      away. For this, these two new functions are well-suited.

    World's ObservedContainer no longer observe.
    
    - This requires CodePatterns 1.3.1 from now on.
    - I had misunderstood what Till had planed with these ObservedContainers for a
      long time: I though they would cause an OBSERVE signal for every iterator
      step but this is not the case. Rather they accumulate all OBSERVE signals to
      have them fire AFTER the loop is done. This is achieved through the depth
      count of the observer protectors.
    - Sadly, this runs against what we do with the lastchangedatom. We need the
      information right away as we the Observer/Observable stuff does not transport
      any information and always updating all is way too costly.
    - Hence, in CodePatterns we have implemented an UnobservedIterator which is
      used in ObservedContainer and does not cause any OBSERVE signals.
    - The source of the problem was createAtom() in a loop over selectedAtoms
      and these atoms not getting created (w.r.t QtInstanceBoard) before the
      molecule's got note of it (cause they are at depth 1).
