* Structs and wire messages for HTLCs * Wire protocol for a state machine with no blocking(!!!) (I will write the state machine) TL;DR: Can do multiple HTLC modifications in-flight, dead simple wire protocol. Both sides can update their Commitments unliaterally without waiting for the other party's signature. Will have basic/preliminary notes in the README * Added **swp to .gitignore because of vim annoyances
