Wrapper for posting to PyHOGS

I've just written a post on how to post to pyhogs.  If either of you, JPaul or Earle, have any changes or additions, then please just add them.  I'm not sure I'm using the proper nomenclature for a number of things, and my explanations for why something works or how to do it are surely not 100% accurate.  If so, add your names to the wrapper .md file.
