Feature Enhancement: Added Conf2JSON class.
Added Henry Winterbottom's produtil changes from HWRF
to the NCEPLIBS-pyprodutil repository.

The enhancement to produtil may be useful for other users
of the produtil package and it also allows for direct syncing
of the HWRF's produtil with the NCEPLIBS-pyprodutil, as the
produtil directories will now be the same, (at least for now).

Changes still need to be tested by other produtil users, accepted and than
committed to the VLab NCEPLIBS-pyprodutil git repository.
