* WalletSimple
* ============
*
* Basic multi-signer wallet designed for use in a co-signing environment where 2 signatures are required to move funds.
* Typically used in a 2-of-3 signing configuration. Uses ecrecover to allow for 2 signatures in a single transaction.
*
* The first signature is created on the operation hash (see Data Formats) and passed to sendMultiSig/sendMultiSigToken
* The signer is determined by verifyMultiSig().
*
* The second signature is created by the submitter of the transaction and determined by msg.signer.
