HeaderParser: A new subclass of Parser which only parses the message

headers.  It does not parse the body of the message, instead simply
assigning it as a string to the container's payload.  This can be much
faster when you're only interested in a message's header.

This class can be used if all you're interested in is the headers of a

simply makes it available as a string payload.
Parsing with this subclass can be considerably faster if all you're
interested in is the message headers.
