Group Currency Token Smart Contract

A group currency would define a number of individual Circles tokens directly or transitively (all accounts trusted by account X) as members. All of those members Circles could be used to mint the group currency.

Note: The GroupCurrencyToken contract is WIP, non-tested, non-audited and not ready for Mainnet/production usage!

Call Flows for direct minting and delegate minting

Direct Minting (Token was trusted by addMember)

Delegate Minting (Token is trusted by delegateTrust)
