 Compared to the original `Super721` implementation that this contract forked
 from, this is a very pared-down contract that includes simple delegated
 minting and transfer locks.
 
 This contract includes the gas efficiency techniques graciously shared with
 the world in the specific ERC-721 implementation by Chiru Labs that is being
 called "ERC-721A" (https://github.com/chiru-labs/ERC721A). We have validated
 this contract against their test cases.
