now thrown randomly across each triangle instead of only at the center of each triangle. all of the rendering kernels have been rewritten so that they operate additively; for example, you may now throw photons from the light source onto the scene, render from the camera to the scene, then throw more photons and render again.

PMTs in the right place and acrylic vessel. No new material properties
yet.

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.

on a profile of the PMT model (see build_pmt() in solids/pmts.py). triangle intersection now allows one of the two coefficients multiplying the vectors which span the triangle to float slightly negative (up to -EPSILON; EPSILON is defined in src/intersect.h) in order to eliminate rays passing through the line between two triangles. cleaned up a lot of unused code. pulled duplicate code in view() and render() into functions in view.py. in order to allow view.py and render.py to search pre-defined geometries, solids, meshes, etc. without requiring them to be pre-built, pre-defined geometries, solids, meshes, etc. should be returned by a function tagged by the decorator @buildable(identifier) defined in view.py, where identifier is a string used to identify the object as an argument to either view.py or render.py. optical materials and surfaces are now defined in optics.py. added an image directory to save cool screenshots.

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.

Modify LBNE class to take a cut_pmt option to switch to cut PMT model.
Add corresponding lbne_cut, minilbne_cut, microlbne_cut detectors.

geometry.py and moved instances of these classes into separate folders. the Solid object no longer contains a rotation, displacement, or id variable; instead, they are passed to a geometry object when calling add_solid().
