thermalfiterrpt.C does 4 things:
1. take the mt spectra of particles (pi+, pi-, K+, K-, p, pbar) and 
convert them into pt spectra
2. apply thermal (bose-einstein and fermi-dirac) fits and gaussian fits
3. calculate <pt> by performing two integrals: int(x*y)dx and int(y)dx
4. calculate errors of mean pt by varying the fit parameters randomly and 
calculate the deviations of the <pt> values

run this code by doing
	source thermalfiterrpt.lsf

the output text files will be created in the same location as the 
corrYields_0.5sig.root

the code meanpt.C will read theses text files and plot <pt> vs. h-
