-
- This routine performs Text::Template parsing on the template and then
- imports the results into a MIME::Entity so we can really use it
-
- Takes a hash containing Argument, TicketObj, and TransactionObj. TicketObj
- and TransactionObj are not mandatory, but highly recommended.
-
- It returns a tuple of (val, message)
- If val is 0, the message contains an error message
