2011-09-08	Geometry.build() waits until a certain number of triangles are grouped ↵	Anthony LaTorre
	together before creating leaf nodes in the bounding volume hierarchy.
2011-09-08	add a useful create_context() function to gpu.py which will take over the ↵	Anthony LaTorre
	current GPU class. get full path name for cuda source inclusion in get_cu_module() and get_cu_source() so that it works when called from outside the package directory.

2011-09-08	Make water the default material for the SNO detector	Stan Seibert

2011-09-07	fix bug in searchsorted() so that it properly searches a descending array.	Anthony LaTorre

2011-09-06	fix devious assumption in searchsorted that if searching a length one array ↵	Anthony LaTorre
	it assumed the array was meant to be in descending order; it now assumes ascending order and this assumption is documented.
2011-09-06	make min_distance argument to intersect_node() optional.	Anthony LaTorre

2011-09-06	add default size for view().	Anthony LaTorre

2011-09-06	geometry on the GPU is now a struct created in the GPUGeometry class. coding ↵	Anthony LaTorre
	style for cuda code is now compliant with python PEP 7 -- Style Guide for C Code.

2011-09-03	add mesh_from_stl() to sphinx documentation.	Anthony LaTorre

2011-09-03	Camera class accidentally used some global variables.	Anthony LaTorre

2011-09-03	update documenation in geometry.py.	Anthony LaTorre

2011-09-03	merge	Anthony LaTorre

2011-09-03	add intro to sphinx documentation from the bitbucket wiki and add some ↵	Anthony LaTorre
	entries to the table of contents.
2011-09-03	initial sphinx documentation.	Anthony LaTorre

2011-09-03	Simulation.simulate() now accepts event.Vertex objects.	Anthony LaTorre

2011-09-03	merge	Stan Seibert

2011-09-03	GPU-based sampling from an arbitrary distribition.	Stan Seibert
	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
2011-09-02	update event structure. break gpu.GPU class into separate smaller ↵	Anthony LaTorre
	independent classes.
2011-08-29	add generator which yields drawn randomly from a histogram interpreted as a pdf.	Anthony LaTorre

2011-08-26	photon object initializes any arguments not passed when initialized. ↵	Anthony LaTorre
	camera.EventViewer uses new fileio.root.RootReader class.
2011-08-26	add repeat_func() to itertoolset.	Anthony LaTorre

2011-08-26	cleanup repeating_iterator() docstring.	Anthony LaTorre

2011-08-26	vertex.isotropic() yields values from transform.uniform_sphere()	Anthony LaTorre

2011-08-26	delete threadtest.py and gputhread.py.	Anthony LaTorre

2011-08-26	add support for magenta and green 3d glasses.	Anthony LaTorre

2011-08-26	no more 3d headache! 3d viewing angle changes depending on the distance to ↵	Anthony LaTorre
	the object in the center of the screen.
2011-08-25	merge	Anthony LaTorre

2011-08-25	add 3d support to camera views by displaying images as an anaglyph. alpha ↵	Anthony LaTorre
	coloring is now calculated using the new searching/sorting algorithms.
2011-08-25	in miniclean geometry, make outer sphere transparent and change polygon face ↵	Anthony LaTorre
	color.
2011-08-25	reshape float3 array returned by to_float3() in gpu.py	Anthony LaTorre

2011-08-25	add library for projecting rays in different ways.	Anthony LaTorre

2011-08-25	add cuda sorting/searching algorithms in src/sorting.h	Anthony LaTorre

2011-08-25	A new PDF evaluation method that does not require storage proportional	Stan Seibert
	to [number of bins] * [number of PMTs]. Instead we accumulate information as the Monte Carlo runs in order to evaluate the PDFs only at the points required for the likelihood calculation. This new interface has been propagated all the way up from the GPU class through the Simulation class to the Likelihood class. We have preserved the full binned histogram implementation in case we need it in the future.
2011-08-23	Add a RootReader class that also functions as an iterator, also create	Stan Seibert
	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!
2011-08-23	Fix Likelihood to use self.sim instead of the global sim, so now it	Stan Seibert
	imports properly. Also correct a units bug in the default time range for the PDFs. We work in units of seconds, not nanoseconds!
2011-08-22	Oops, uncomment other benchmark tests	Stan Seibert

2011-08-22	Use PDF created on GPU in likelihood calculation. This is 11x faster than ↵	Stan Seibert
	before.
2011-08-22	Benchmark and unit test for PDF creation	Stan Seibert
