- Update to current master.
- Move SGroup parse time checks to SGroupChecks namespace.
- Store SGroups in ROMOl as vector<SGroups>.
- SGroup methods return referenes instead of pointers.
- Use atom/bond/sgroup indexes for properties instead of pointers.
- Have SGroups inherit from RDProps; move properties to RDProps.
- Remove trivial/unused methods.
- Add a link to the SD specification atop SGroup.h
