Detailed Description

Implements minimal client-oriented Generic TLV capabilities.

This file implements minimal Generic TLV capabiliies for a client - enough for it to be able to understand and validate a generic TLV packet structure, iterate through these generic TLVs, and return any particular TLV. For the most part, these TLVs correpond to our Frame class objects.
