+ * @dev If the signature is from one of the authorized bouncer addresses, the signature
+ * @dev is valid. The owner of the contract adds/removes bouncers.
+ * @dev Bouncer addresses can be individual servers signing grants or different
+ * @dev users within a decentralized club that have permission to invite other members.
+ * @dev
+ * @dev This technique is useful for whitelists and airdrops; instead of putting all
+ * @dev valid addresses on-chain, simply sign a grant of the form
+ * @dev keccak256(`:contractAddress` + `:granteeAddress`) using a valid bouncer address.
+ * @dev Then restrict access to your crowdsale/whitelist/airdrop using the
+ * @dev `onlyValidSignature` modifier (or implement your own using isValidSignature).
+ * @dev
+ * @dev See the tests Bouncer.test.js for specific usage examples.
