2011-06-18	change curandstate array length to 100,000. gputhread.run() now correctly ↵	Anthony LaTorre
	initializes ALL of the states.
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.
2011-06-12	added some fun models; added some untested code to implement absorption, ↵	Anthony LaTorre
	scattering, reflection, and refraction
2011-06-07	Switch triangle texture to device array, use int32 and float32	Stan Seibert
	datatypes everywhere, and build final mesh without concatenation of lists. This allows for very large detectors, like full size LBNE.
2011-06-03	load material/surface index lookup arrays to the gpu and bind them to ↵	Anthony LaTorre
	textures. also, forgot to include the gpu code for material/surface structures
2011-06-03	load materials/surfaces onto the gpu	Anthony LaTorre

2011-06-02	material/surface codes or color are packed into the fourth byte of the ↵	Anthony LaTorre
	triangle data texture depending on the color keyword passed to Geometry.build()
2011-06-02	triangle mesh is now stored everywhere as a split list of vertices and triangles	Anthony LaTorre

2011-06-01	first step towards moving to a new mesh/solid/geometry structure	Anthony LaTorre

2011-05-27	kernel ran off the end of the ray array	Anthony LaTorre

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

2011-05-20	faster bounding volume hierarchy construction	Anthony LaTorre

2011-05-18	added test likelihood	Anthony LaTorre

2011-05-18	added some more documentation and a more accurate miniature version of lbne	Anthony LaTorre

2011-05-17	added documentation	Anthony LaTorre

2011-05-16	added stl mesh viewer	Anthony LaTorre

2011-05-15	cleanup. fixed tests	Anthony LaTorre

2011-05-15	new geometry class. beginning to implement physics by defining a material ↵	Anthony LaTorre
	class; each triangle will have a material linked to both of its sides
2011-05-13	use floats	Anthony LaTorre

2011-05-13	added a bounding volume hierarchy	Anthony LaTorre

2011-05-10	move triangles to mesh	Anthony LaTorre

2011-05-09	pull triangle vertices in kernel function	Anthony LaTorre

2011-05-09	improve triangle intersection algorithm by allowing it to terminate early	Anthony LaTorre

2011-05-09	use pixel pointer instead of pixel array	Anthony LaTorre
