2021-05-09	Write t0 for primary vertex to ROOT file and fix unit test to catch this.	Stan Seibert

2011-10-07	Create a Detector class to hold information about the PMTs in a	Stan Seibert
	geometry, like the mapping from solid IDs to channels, and the time and charge distributions. Detector is a subclass of Geometry, so that a Detector can be used wherever a Geometry is used. Only code (like the DAQ stuff) that needs to know how PMT solids map to channels should look for a Detector object. There is a corresponding GPUDetector class as well, with its own device side struct to hold PMT channel information. The GPU code now can sample an arbitrary time and charge PDF, but on the host side, the only interface exposed right now creates a Gaussian distribution.
2011-10-05	Epic port of Chroma from units of meters/seconds/MeV to	Stan Seibert
	millimeters/nanoseconds/MeV in order to match GEANT4, and also avoid huge discrepancies in magnitude caused by values like 10e-9 sec. Along the way, cleaned up a few things: * Switch the PI and SPEED_OF_LIGHT constants from double to single precision. This avoid some unnecessary double precision calculations in the GPU code. * Fixed a silly problem in the definition of the spherical spiral. Now the demo detector looks totally awesome. Also wrapped it in a black surface. Demo detector now has 10055 PMTs. * Updated the test_ray_intersection data file to reflect the new units. * Fix a missing import in chroma.gpu.tools
