+ * 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.
+ *
+ * Data Formats
+ * ============
+ *
+ * The signature is created with ethereumjs-util.ecsign(operationHash).
+ * Like the eth_sign RPC call, it packs the values as a 65-byte array of [r, s, v].
+ * Unlike eth_sign, the message is not prefixed.
+ *
+ * The operationHash the result of keccak256(prefix, toAddress, value, data, expireTime).
+ * For ether transactions, `prefix` is "ARBETH".
+ * For token transaction, `prefix` is "ARBETH-ERC20" and `data` is the tokenContractAddress.
