tension of ERC20 to support Compound-like voting and delegation.

NOTE: If exact COMP compatibility is required, use the {ERC20VotesComp} variant of this module. This extension keeps a history (checkpoints) of each account's vote power. Vote power can be delegated either by calling the {delegate} function directly, or by providing a signature to be used with {delegateBySig}. Voting power can be queried through the public accessors {getVotes} and {getPastVotes}. By default, token balance does not account for voting power. This makes transfers cheaper.
