Pyang

cleaned everything up and added to README file. Will probably need to add some more comments to the code but for now, it seems ok
I know this has already been merged, but as an fyi, this isn't the best way to do this.  It's error prone.  Create a hash instead

> require 'uri'
> a = {:name_first => 'Jeff', :name_last => 'Behl', :name_full => 'Jeff Behl' }
> URI.encode_www_form( a )
 => "name_first=Jeff&name_last=Behl&name_full=Jeff+Behl"
