the draw_axis.tcl script is a little bit more generalize now
Added test files to start doing the boltzmann weighted cpp code
Merge branch 'boltzmann_in_cpp' of https://github.com/webbgroup-physical-chemistry/GroupCode into boltzmann_in_cpp
Classes to parse through most of the usual inputs have been created.  I still need one to parse through the list.file file.  I would also like to add the option to a) make a file for each xvg file which is the probability of that frame and b) repeat the Boltzmann-weighting calculation using a series of [<.xvg> <.frameprob>] files.  That might be trickier.  Also, I'd like to use threading for reading in the series of data files
