Lookup element by its symbol?

[caseykneale]

It'd be really nice to have built in constructors/convenience functions that query available atoms for a given property.

IE:

PeriodicTable.Elements("H") == PeriodicTable.Elements(Hydrogen)

or

lookitup(symbol) = [ e for e in PeriodicTable.elements if e.symbol == symbol][1]
e = lookitup("H")

I'm kicking around a package that might benefit from this...

This is implemented as

elements[:ElementSymbol]

forgot about this! Thanks!
