Detailed Description

singleton class for retrieving information about atoms

Use the singleton like this:

    const PeriodicTable *tbl = PeriodicTable::getTable();
    tbl->getAtomicWeight(6); // get atomic weight for Carbon
    tbl->getAtomicWeight("C"); // get atomic weight for Carbon

bool RDKit::PeriodicTable::moreElectroNegative	(	UINT	anum1,
		UINT	anum2
	)			const `[inline]`

convenience function to determine which atom is more electronegative

check if atom with atomic number anum1 is more electronegative than the one with anum2 this is rather lame but here is how we do it

the atom with the higher number of outer shell electrons is considered more electronegative
if the # of outer shell elecs are the same the atom with the lower atomic weight is more electronegative
