2011-09-10	new alpha rendering scheme.	Anthony LaTorre

2011-09-10	change color of pmt shell.	Anthony LaTorre

2011-09-09	chroma-cam script now used to view geometries.	Anthony LaTorre

2011-08-17	import chroma modules from subpackages with import chroma.module_name	Anthony LaTorre

2011-08-16	add linear_extrude() function to make.py. rotate_extrude() now takes the ↵	Anthony LaTorre
	number of rotational steps to extrude instead of the angle step size. updated documention in make.py.
2011-08-08	add a simple event viewer. view events by running ./camera.py ↵	Anthony LaTorre
	<detector_name> -i <name_of_io_file>.
2011-08-05	speedup bounding volume construction of leaf nodes by taking the min and max ↵	Anthony LaTorre
	of ungrouped instead of grouped vertices from a mesh
2011-07-27	Use the more realistic SNO database and add PMT concentrators.	Stan Seibert

2011-07-19	removed STL pmt models; pmt models are now built by calling rotate_extrude() ↵	Anthony LaTorre
	on a profile of the PMT model (see build_pmt() in solids/pmts.py). triangle intersection now allows one of the two coefficients multiplying the vectors which span the triangle to float slightly negative (up to -EPSILON; EPSILON is defined in src/intersect.h) in order to eliminate rays passing through the line between two triangles. cleaned up a lot of unused code. pulled duplicate code in view() and render() into functions in view.py. in order to allow view.py and render.py to search pre-defined geometries, solids, meshes, etc. without requiring them to be pre-built, pre-defined geometries, solids, meshes, etc. should be returned by a function tagged by the decorator @buildable(identifier) defined in view.py, where identifier is a string used to identify the object as an argument to either view.py or render.py. optical materials and surfaces are now defined in optics.py. added an image directory to save cool screenshots.
