	* This version has many improvements over the original @izqui's library like using REVERT instead of THROWing on failed calls.
	* It also implements the awesome design pattern for initializing code as seen in Gnosis Safe Factory: https://github.com/gnosis/gnosis-safe-contracts/blob/master/contracts/ProxyFactory.sol
