Update 10.21.2013 1756

cmp_speed.cc:			Added some test parameters
speed_test.cc:			Tested speed of fast_2d
datagrid_test.cc:		Tested accuracy of fast_2d
reflection_model.cc:	Added new debug statements
wave_queue.cc:			Added new debug statements
wave_front.cc:			Added new debug statements
fast_2d.cc:				Create all derivatives and cross derivatives at construction
						now instead of on each call. Upon call, reference the data
						from the matrix created at construction. This was done in
						the hopes of increasing speed. Testing still required to
						confirm.
fast_3d.cc:				Changed slope calc for pchip part and derv. Further testing
						is required to varify accuracy and speed. Preliminary change
