Cloned march_script_generator.py from cygob7_jjh_script.py.

Re-wrote the top-level docstring, but didn't touch any code yet.
Removed the tables() function because we don't want that code here.
Reorganized the script into a single function. \n More structural updates to come.
Did a crazy amount of redesigning. Current version makes non-phased LCs.
Added 'custom_xlabel' keyword to all of the lc() calls. They were missing.
Now we only generate the EPS figures, to save time and CPU.
Added phase code to do_it_all_cygob7
