//! Does some cleanup operations on the molecule to prepare it to draw nicely
/*
The operations include: kekulization, addition of chiral Hs (so that we can draw
wedges to them), wedging of bonds at chiral centers, and generation of a 2D
conformation if the molecule does not already have a conformation

\param mol: the molecule to be modified
\param kekulize: toggles kekulization (this can fail, see below)
\param addChiralHs: adds Hs to the graph on chiral atoms
\param wedgeBonds: calls WedgeMolBonds()
\param forceCoords: generates a 2D conformation even if one is present already

NOTE: the kekulization step can fail, throwing a MolSanitizeExecption. If this
happens the molecule will be in an inconsistent, partially kekulized, state.
This isn't normally a problem for molecules that have been sanitized, but can be
problematic if the molecules have been modified post santitization.
