/*****************************************************************
 *   This is the main Rocket Pool Token (RPL) contract. It features
 *   Smart Agent compatibility. The Sale Agent is a new type of 
 *   contract that can authorise the minting of tokens on behalf of
 *   the traditional ERC20 token contract. This allows you to 
 *   distribute your ICO tokens through multiple Sale Agents, 
 *   at various times, of various token quantities and of varying
 *   fund targets. Once you’ve written a new Sale Agent contract,
 *   you can register him with the main ERC20 token contract, 
 *   he’s then permitted to sell it’s tokens on your behalf using
 *   guidelines such as the amount of tokens he’s allowed to sell, 
 *   the maximum ether he’s allowed to raise, the start block and
 *   end blocks he’s allowed to sell between and more.
