Claim Contract

Users will claim their governance rewards using this contract. Any time a claimable balance is touched, Claim will be invoked in order to keep proper track of issuance. This contract also handles updating YBX issuance amounts for each daily period. Any other contracts that manipulate claimable balances will have the Claim contract invoked to keep proper track of issued pool incentives.
