ecrecover

FFI export of Ethereum's ecrecover, with Erlang integration.

prerequisite:

a checked out copy of my fork of parity-ethereum (https://github.com/johnsnewby/parity-ethereum) checked out in the same directory this is (i.e. it will be referenced as ../parity-ethereum)

to compile: cargo build make (automatically runs tests).

to test: make test (requires gcc)

(if you don't see Test passed then something went wrong).
