	the GPU, and run the DAQ multiple times on the same photons in a likelihood calculation. Propagating the same photons in a warp speeds up propagation by a factor of 3 (and we could do this even better if we wanted), and this improves the statistics in a likelihood evaluation quite a bit. Running the DAQ multiple times is also an inexpensive way to improve the quality of the PDF estimates.

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.
