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

2011-08-25	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

2011-08-22	Expose interface to PDF creation on the GPU in the Simulation class.	Stan Seibert

2011-08-22	Enable creation of charge and time PDF on GPU	Stan Seibert

2011-08-21	nreps was not actually being used properly by the Simulation class	Stan Seibert

2011-08-21	Add new nreps parameter to Simulation.simulate() to allow the same initial ↵	Stan Seibert
	photon distributions to be propagated multiple times. Default nreps is 1.
2011-08-21	Repeating iterator that returns the item from the parent iterator multiple ↵	Stan Seibert
	times before moving to the next element.
2011-08-20	fix bug in Likelihood class; pdfs for each pmt were the same histogram	Anthony LaTorre

	photons when the parent particle is at (1,0,0)
2011-08-20	A simple unit test of the constant particle gun	Stan Seibert

2011-08-20	Assign base RNG seed when none is given in G4ParallelGenerator.	Stan Seibert
