error.go

Adding identification of aborts per section 4.1 of the paper. A pair of ECDSA keys is created in round 1 for player authentication. It signs the Paillier public key first. It then signs the shares in round 2. In case the Feldman check fails in round 3, evidence is broadcasted. Round 4 is now split into normal logic and handling an abort. When handling the abort, an independent player (not the plaintiff, not the accused one) will re-verify the signature of the share and re-check the Feldman shares. The outcome of the abort identification may indeed blame the accused party if the Feldman check fails, or else it may blame the plaintiff for trying to frame the accused party.
