I've got 3 different Word templates that I have as resource files.  I
know that I can pull them in from the assembly by using
GetManifestResourceStream (at least I think this is the method to use)
and that the assembly object should be from GetExecutingAssembly.
I have a document object that is WordDoc that is a new Document()
type.

How do I do the WordDoc.Documents.Add ?  Normally, using this
function, the first argument would be the filename of a word template
on disk.  Since I'm pulling in from a resource file
(GetManifestResourceStream), how do I add this template to the
WordDoc.Documents collection?
