Permit Extension for EIP-20 Signed Approvals

ERC 2612, Permit Extension for EIP-20 Signed Approvals. Arguably one of the main reasons for the success of EIP-20 tokens lies in the interplay between approve and transferFrom, which allows for tokens to not only be transferred between externally owned accounts (EOA), but to be used in other contracts under application specific conditions by abstracting away msg.sender as the defining mechanism for token access control.
