This function is very similar to OETriposAtomTypeNames, and sets the
atom type name string property using OEAtomBase SetType. However,
instead of doing graph matching to perceive the Tripos atom types, it
assumes OETriposAtomTypes has already been called. This is a simple
optimization, that avoids duplicating effort and just sets the atom
type name string property from the value stored in
The atom type name string property should typically be set to a Tripos
type name before writing a Sybyl .mol2 file using the low-level
OEWriteMol2File function.
