chroma/tests, branch master

Move CUDA source inside chroma package, rename tests directory to test

2011-09-16T19:02:02+00:00

add chroma-sim script. get rid of GPU class; contexts should now be created with create_cuda_context().

2011-09-12T20:41:17+00:00

add ray_intersection unit test.

2011-09-10T20:21:21+00:00

geometry on the GPU is now a struct created in the GPUGeometry class. coding style for cuda code is now compliant with python PEP 7 -- Style Guide for C Code.

GPU-based sampling from an arbitrary distribition.

2011-09-03T13:19:55+00:00

The sample_cdf() device function will draw random numbers from an arbitrary
disribution given a cumulative distribution function in the form of
a list of x,y points, beginning with y=0 and ending with y=1.  For an
example of how to convert a ROOT histogram to this form, see the unit
test in test_sample_cdf.py

update event structure. break gpu.GPU class into separate smaller independent classes.

Add a RootReader class that also functions as an iterator, also create

2011-08-23T23:28:36+00:00

a simple unit test for event reading and writing.  There were several
minor I/O bugs that are now fixed!  Always test your code, kids!
