Since the RSLHelper class and it's "rsl" methods do not actually operation of
GT2 RSL documents but rather GT4 job description documents, the should be
renamed to be more accurate.  The following tasks need to be done:

1) Rename RSLHelper to JobDescriptionHelper
2) Change all occurances of "rsl" in RSLHelper's method names to "jobDescription".
3) Change all references to this class and it's methods in the code.
4) Change the Java scenario documentation to use the new names.
