* Adjusting version
* Initiating some edoc stuff
* Doc check
* Fixing docs
* Do a hard type check when entering nodes
* Two fixes:
- Module call change from enacl to ecu_eddsa
- Fix the v3 call endpoint for top block
* Fix top_block typespec and make top_height great again
* Fix typo
* Fix handle_down error message
It was printing a tuple with `~s`, and also tried to pretty print a fat
call stack more than a hundred columns into the first line, which put
together made for some confusing exception-during-error-handling
messages in the erlang console.
* Switch to unicode formatting in handle_down
