DESCRIPTION:
Declaration of cProtocolEntityFieldEnumerator
PUBLIC CLASSES AND METHODS:
cProtocolEntityFieldEnumerator
Class to navigate a protoocl entity, generating a vector of
field IDs, i.e. every field referenced by this protocol entity
in the exact order it would regularly be found
NOTE: This only functions for fixed structures such as NV items
