2011-10-05	Missing glass parameter in build_pmt_shell()	Stan Seibert

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

	channels.
2011-10-05	The demo/detector.py module is no longer used.	Stan Seibert

2011-10-05	Default values for required arguments in the make.* functions creates confusion.	Stan Seibert

2011-10-05	Add tlatorre/histogram as a subrepository so that we can use it in the ↵	Stan Seibert
	Rayleigh scattering unit test
2011-10-05	Kernel estimation implementation for calculating PDFs at each PMT.	Stan Seibert
	A little rough around the edges, and still needs some development work.
2011-10-05	Calling the garbage collector explicitly is very expensive and gets ↵	Stan Seibert
	progressively slower the longer the program runs. Need to find another way to deal with running out of GPU memory due to reference cycles in PyCUDA.
2011-10-03	Split out CUDA PDF functions into separate .cu file.	Stan Seibert

2011-10-03	Output device usage to logger.	Stan Seibert

2011-10-03	Create a chroma.log module that provides the default logger object for	Stan Seibert
	the package. Rather than use the logging module directly, we wrap it with this to ensure that logger.basicConfig() is called automatically. All chroma code should use this logger for printing status information so that it can be hidden when chroma is part of a bigger application.
2011-09-30	Test if root.C classes have been loaded before loading in root.py. Prevents ↵	Stan Seibert
	printed warnings when the user already has a .rootlogon.C to load the Chroma ROOT classes.
2011-09-30	ROOT sucks and the TApplication object created by PyROOT interprets	Stan Seibert
	the contents of sys.argv whether you want it to or not. A simple hack is to blank out sys.argv around the point where you import ROOT. As an additional requirement, you have to actually use the ROOT module for something (even just looking up a class) in order for the TApplication to be initialized, so you can't just replace sys.argv with an empty array around the ROOT import. To ensure this is always done correctly, all Chroma modules that need ROOT should obtain it by: from chroma.rootimport import ROOT

2011-09-29	Remove MiniCLEAN	Stan Seibert

2011-09-29	Abolish chroma.optics. Material properties are entirely detector	Stan Seibert
	specific, so now the example materials and surfaces are found in chroma.demo.optics.
2011-09-29	Fix imports in __init__.py	Stan Seibert

2011-09-29	New demo detector for Chroma that is not dependent on any internal ↵	Stan Seibert
	experiment information.

2011-09-19	Remove unused imports	Stan Seibert

2011-09-17	Split up chroma.gpu into separate modules. chroma.gpu.__init__ imports ↵	Stan Seibert
	everything from the sub modules, so usage is the same.
2011-09-17	Module for fitting and evaluating multi-dimensional parabolas	Stan Seibert

2011-09-17	.chroma directory is now used to build the ROOT shared library describing ↵	Stan Seibert
	the event data structure. No more writing files to chroma package directory.
2011-09-16	Rename chroma.fileio to chroma.io	Stan Seibert

2011-09-16	Silence annoying GEANT4 warnings and banners during operation.	Stan Seibert

2011-09-16	Remove executable flag from camera.py and sim.py, which are no longer scripts.	Stan Seibert

2011-09-16	Add a srcdir attribute to the chroma.cuda module. This consolidates the ↵	Stan Seibert
	calculation of the path to the CUDA source code in one place.
2011-09-16	Fix reference to _g4chroma module	Stan Seibert

2011-09-16	Now use setuptools-built Boost::Python GEANT4 module	Stan Seibert
