GenGORankedEnrichment class file w/ command line

Modified the hdf_program02.py file to the GenGORankedEnrichment.py file.
Removed global variables (bad programming style)
Moved imports to the top (more standard, faster)
Added command line support.
The process now takes as additional input a file that represents the
demarcation of the gene sets.
It takes a standard list of genes together with a quality score for each
gene now.
Moved old files to Old Stuff folder
