FmpPayloadHeaderLib

Provides services to retrieve values from a capsule's FMP
Payload Header. The structure is not included in the
library class. Instead, services are provided to retrieve
information from the FMP Payload Header. If information is
added to the FMP Payload Header, then new services may be
added to this library class to retrieve the new information.
