claimAndRepay() - Shows an Arbiter taking a Borrower’s revenue from their Spigot, trading it on 0x protocol to the token they’re currently borrowing, and immediately pays down debt to next lender in queue.SpigotedLine's claimAndRepay operates similarly to claimAndTrade, but includes the additional step of repaying part of, or the entire, loan. It could be thought of as claimAndTradeAndRepay. Like claimAndTrade, the function claims (fetches/transfers) earned revenue tokens from the Spigot to the SpigotedLine - these need to have been claimed/sent by the revenue contract to the Spigot in advance. This increases the unused token balance. This example demonstrates using an ERC20 token, such as $USDC or $DAI, as the credit token, and native $ETH as the revenue token generated by the borrower's revenue contract.
