Initial commit of interim spec template and mostly-but-not-entirely-finished key reset specification draft. N.B.: Key reset spec is intended to give an example for future specs of *as-yet-unimplemented* protocols, since there was some disagreement on what is necessary. Since it has already been implemented, there will be several sections missing that are in the initial template.
Start from the initial template, and use what you need! Each specification is different. Necessary, though, are the problem framing, examples and the requirements they drive, and the response to those examples in the protocol description section.
Anyway, not complete. Just archived for now.
