Notes for swap changes
View swap_notes.txt
Peer should implement a send method. (as a p2p/Protocol msg Type)
Swap should be a protocol (p2p/Protocol) that the peer implements.
Swap protocol should have 2 messages (payment request, and payment)
Eliminate the 'proto' interface e.g. `self.proto.Pay(-self.balance, promise)`
This next section basically is to say, don't let the cheqbook deployment and interface logic get in the way of the developement of implementing Swap.
Leave cheque book deployment alone.
Could draft how to simplify the cheqbook.
A simplified version of the cheqbook will be deployed.
View swap_progress.md

Some significant changes that impact the swap implementation are the restructuring of protocols found in swarm/network/protocol.go So far I have added back swap specific properties to the Bzz Struct and Peer Struct.

Right now, everything compiles and runs - but when I connect two swarm peers there is not any swap accounting happening. This is to be expected because I haven't yet implemented the swap instances on the Bzz or Peer Structs. I am planning to begin implementing this here

Would you mind taking a quick look at what's been done so far and help me understand if I'm headed the right direction, or if I'm way off in my approach thus far. And
