2011-07-10	added a hybrid monte carlo ray tracing rendering algorithm	Anthony LaTorre

2011-06-24	argument '-j' to threadtest.py now specifies a list of device ids to be ↵	Anthony LaTorre
	used. GPUThread objects now shallow copy the geometry so that threads are not writing to the same memory when the geometry is loaded onto the gpu. the model number for the 12" Hamamatsu PMT is R11708, not r7081 (which is the model for the 10" PMT); all references to the 12" PMT were changed accordingly. only allocate space for 20 materials and 20 surfaces on the gpu instead of 100 to save some space. started to modify track.py to build its own photons and module since the GPUThread object only copies photon hit times back from the gpu (not track information), but I am waiting to find out if pycuda GPUArrays can be used with vector types.
2011-06-23	move photon initialization to the gpu. it's unclear if this is a speed ↵	Anthony LaTorre
	improvement.
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.
2011-06-18	change curandstate array length to 100,000. gputhread.run() now correctly ↵	Anthony LaTorre
	initializes ALL of the states.
2011-06-18	forgot to initialize gpu random number states in gputhread.run()	Anthony LaTorre

2011-06-17	visually tested optics code. added models of the inner and outer meshes for ↵	Anthony LaTorre
	the 12" hamamatsu and sno pmts. ratdb.py is able to parse ratdb files. chromaticity.py provides a function to map wavelength -> rgb color. lbne detector model now includes an outer black cylinder and pmts with a glass layer and photocathode/reflective surfaces.
2011-06-02	triangle mesh is now stored everywhere as a split list of vertices and triangles	Anthony LaTorre

2011-05-31	you can now specify block size for a gputhread	Anthony LaTorre

2011-05-23	lbne model now imports python modules directly	Anthony LaTorre

2011-05-22	gpu threads	Anthony LaTorre
