​ Abstract smart contract to extend ERC20s, in order to add streamings capability.

Each streaming contains an amount per second, a starting date, and ending date, a sender an a receiver. Can only exist one streaming between to addresses.

A flow between to addresses is a directed relationship which summarizes the streamings where sender address is the flow sender, and receiver address is the flow receiver. This concept allows to scale consulting over balances, because the contract doesn't need to loop over strreamings. ​
