: solve the Atom, Bond problem by creating Graph of Atoms within the

Indeed, the Graph seems the most efficient and easiest to adapt Datastructure
to implement atom connectivity. String and or bond-parameters can be linked
with the node connections.
One should also consider if a molecule , or a subunit of a molecule, should
be implemented as a set of residues or a set of atoms. The residue
implementation should work faster when handling major parts of the molecule.
The set of atoms inplementation on the other hand has advantages for selecting
atoms rather than residues.
