Detailed Description

Return an enumeration of the headers of an RFC-822 style message.

This implementation assumes that the headers have already been separated from the body, so that the input stream passed to the HeaderEnumeration constructor returns only the header portion of the message.

XXX It would be pretty easy to have this class detect the CRLF, CRLF sequence that ends the headers, as well....
