Updated the Makefile to make create_hv_mesh object file. Moved the main of create_hv_mesh into sweep.cpp. Removed the automatic running of sweep and the section for scripts (no longer using these, thank goodness).
Changed the name of create_hv_mesh to hv_mesh_gen.
Removed the compilation of the hv_mesh_gen header file.
Re-wrote the gnuplot script function. Its much simpler now due to the structure of the data file.
Corrections to formatting of the data file.
Added a section for generating the full plot data file for timing of the ray fires.
Changed the name of the section for plot prep in the Makefile. Its making a new plot datafile, not a script.
Added git ignore so I can keep data for later in a separate directory.
