* Dissector for the Skinny Client Control Protocol

* Author: Diederik de Groot <ddegroot@user.sf.net>, Copyright 2014
* Rewritten to support newer skinny protocolversions (V0-V22)
* Based on previous versions/contributions:
* - Joerg Mayer <jmayer@loplof.de>, Copyright 2001
* - Paul E. Erkkila (pee@erkkila.org) - fleshed out the decode
* skeleton to report values for most message/message fields.
* Much help from Guy Harris on figuring out the wireshark api.
