2019-03-23	speed up the likelihood calculation by avoiding calls to acos()	tlatorre
	This commit speeds up the likelihood calculation by eliminating most calls to acos(). This is done by updating the PMT response lookup tables to be as a function of the cosine of the angle between the photon and the PMT normal instead of the angle itself.

2019-03-07	update code to allow you to run the fit outside of the src directory	tlatorre
	To enable the fitter to run outside of the src directory, I created a new function open_file() which works exactly like fopen() except that it searches for the file in both the current working directory and the path specified by an environment variable.

2018-09-11	add PMT response	tlatorre
	This commit adds code to read in the PMT response from the PMTR bank from SNOMAN. This file was used for the grey disk model in SNOMAN and was created using a full 3D simulation of the PMT and concentrator. Since the PMT response in SNOMAN included the quantum efficiency of the PMT, we have to divide that out to get just the PMT response independent of the quantum efficiency. I also updated the likelihood calculation to use the pmt response. Currently the energy is being fit too high which I think will improve when we update the solid angle calculation to use the radius of the concentrator instead of the PMT.
