MID ID Response Capule.

MIDIDResponseCapsules are only created by a MIDIDRequestCapsule that has been delivered to a node that can satisfy the request. MIDIDResponseCapsules contain information describing the MID.

A MIDIDResponseCapsule packet contains the following fields (on top of the base Capsule fields):

• requestMID: MID that initiated the request
• pid: PID associated with the MID.
• userInfo: userInfo (see UserID).

   MIDIDResponseCapsule() 

Construct a blank MIDIDResponseCapsule.

This is only invoked when a MIDIDResponseCapsule capsule is received at a node and the node must construct a capsule before decoding the packet into it.

   MIDIDResponseCapsule(TypeID unknownMID, 
                        TypeID pid, 
                        UserID userInfo) 

Construct a MIDIDResponseCapsule to send back in response to a MIDIDRequestCapsule. Only invoked by MIDIDRequestCapsule.evaluate().
