2011-09-10	update 3d mode to work properly when rendering multiple geometries.	Anthony LaTorre

2011-09-10	merge	Stan Seibert

2011-09-10	Add the ability to propagate the same photons multiple times on the	Stan Seibert
	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.

2011-09-06	fix devious assumption in searchsorted that if searching a length one array ↵	Anthony LaTorre
