	event creation. Now we have vertex generators (that produce initial particles), photon generators (that create photons to propagate), and a standard data structure using Python class containers and numpy arrays to hand around the code. Also cleaned up some naming of things before they become conventions.

	The ROOT data structure has been extended to allow storage of the individual gamma rays as subtracks.

2011-08-03	GEANT4-based photon vertex generator.	Stan Seibert
	Propagates a particle through a huge volume of some material and harvest the photon vertices that are created for propagation with Chroma. Relies on a patched version of g4py, plus a local boost.python module that is built at import time if needed. (Does not detect changes to rebuild, however.) Chroma materials can now have a density set, as well as an elemental composition (by weight) that is used by this generator.
