minor formatting
Config file tests written for step 2.
Revised comments for format/content in source_gamma.F90.
Note on adding r2s-act/scripts to PYTHONPAT
fixed syntax mistake
Merge remote-tracking branch 'origin/master'
Fixed bug in r2s_step2.py refactoring; Comments/docstrings.
Testing for r2s_step2.py
Better explanation of syntax in alara_snippet.
Uniform sampling does void rejection now.
Add simple test for uniform sampling with void rejection; Comment changes for voxel case as well.
Added -r and -a options for resampling, and uniform resampling of entire problem.
Updated tests (WIP) for new flags in source.F90.
Code to generate 'runall' script for a set of step 2 problems.
Removed 'save' block from module in source.F90.
'save' only makes sense in a subroutine, which was the case prior to refactoring in July.  Testing indicates that the 'save' block did indeed affect nothing.
Modification to do parameter reading the same way r2s_step2.py does
Typo fix
Updates to add 'resample' and 'uni_resamp_all' options to r2s-act workflow.
r2s_step2setup now creates the script r2s_run_all_step2.sh which runs r2s_step2.py for all subfolders created. #33
