Okay, this is ready now. This does not need to be perfect with all edge case testing, as it is just a demo contract to prove the point. |

This shows how a contract can verify an Ethereum transaction given the information stored on chain. It is feature complete. We just need to expose
verify_transactionas part of theHandleMsg. Opening a draft to allow early review.It turns out we don't need a DER decoder as the Ethereum nodes provide signatures as three fields (r, s, v) directly.
Closes #753
