 * to contain a specific piece of information about a specific molecule.

 * necessary and we need to know the channels we have to listen to know when an
 * update is necessary.
 *
 * This class takes care of of all the rest:
 * -# informing QtMoleculeList about required update ("dirty")
 * -# relaying updateState() call from QtMoleculeList to the specific internal_updateState()
