// Adds 2D coordinates to a molecule using the Depict.dll
//
// ARGUMENTS:
// mol: the molecule to be altered
// tempFilename: (OPTIONAL) the name of the temporary file
//
// RETURNS:
// 1 on success, 0 otherwise
//
// Here's the process by which this works (it's kind of contorted):
// 1) convert the mol to SMILES
// 2) use the DLL to convert the SMILES to a mol file (on disk)
// 3) parse the mol file into a temporary molecule
// 4) do a substructure match from the old molecule to the
// temp one (which may have a different atom numbering or additional
// atoms added).
// 5) Update the positions of the atoms on the old molecule.
// 6) Free the temp molecule.
//
// NOTES:
// - *FIX:* at the moment we're not doing anything to clear up the
// temp file created in this process. It'll always have the same
// name unless the user explicitly asks that we do something different.
// - To use the DLL, it's essential that the COMBICHEM_ROOT and COMBICHEM_RELEASE
// environment variables be set. If this isn't done, this whole process
// will fail.
// - See the notes above about failures when opening the DLL.
