/*! Instead of sending molecules for output via AddChemObject(), they are
saved in here in OBMoleculeFormat or discarded. By default they are
saved only if they are in the first input file. Parts of subsequent
molecules, such as chemical structure, coordinates and OBGenericData
can replace the parts in molecules with the same title that have already
been stored, subject to a set of rules. After all input files have been
read, the stored molecules (possibly now having augmented properties) are
sent to the output format.
Is a static function with *this as parameter so that it can be called from other
format classes like XMLMoleculeFormat which are not derived from OBMoleculeFormat.
