What you should know if you're constructing

• ISNOWPayDelegates and ISNOWRedemptionDelegates are both sorts of delegates. Any contract adhering to these interfaces may be used as a delegate in the financing cycles of a project.

• The dataSource of the financing cycle should specify which delegated contracts to utilize.

• didPay(...) is invoked in SNOWPayoutRedemptionPaymentTerminal. pay(...), and didRedeem(...) is invoked in SNOWPayoutRedemptionPaymentTerminal.redeemTokensOf(..). (...).

• The redemption delegate hook is called prior to the distribution of monies.
