Reconstitute an entry document from the output of the Universal Feed Parser.
The main entry point is called 'reconstitute'. Input parameters are:
results: this is the entire hash table return by the UFP
entry: this is the entry in the hash that you want reconstituted
The value returned is an XML DOM. Every effort is made to convert
everything to unicode, and text fields into either plain text or
well formed XHTML.
Todo:
