2011-08-09	Store a photon history for each hit channel. If multiple photons hit the	Stan Seibert
	same channel, their history bits are OR'ed together.
2011-08-08	propagate() takes an array of photon offsets and a range of	Stan Seibert
	offsets to load. Now events with more photons than RNG states can be propagated through multiple kernel calls. Also lays the groundwork for consolidating photons between steps to reduce the amount of propagation work required.
2011-08-04	Don't draw a random time delta in the daq kernel unless it is necessary.	Stan Seibert

2011-07-20	pulled a lot of the photon propagation code out of src/kernel.cu into ↵	Anthony LaTorre
	src/photon.h so that photon propagation by propagate() in kernel.cu and the hybrid monte carlo ray tracing use the same code. instead of a single state, photons now carry the history of the processes they've undergone. this history is stored as a bitmask; see src/photon.h. start_node and first_node of the mesh are now stored as global variables in mesh.h instead of being passed to kernel functions.
2011-06-23	move photon initialization to the gpu. it's unclear if this is a speed ↵	Anthony LaTorre
	improvement.
2011-06-22	Start jittering the PMT times in the DAQ simulation.	Stan Seibert

2011-06-21	A GPU-side "DAQ" implementation that identifies the first photon on each ↵	Stan Seibert
	channel, which is presumed to trigger that channel. Major speed up in conversion of detection times to time PDFs.
