/**
 *      BASE:      ERC721A
 *      EXTENSION: LazyMint
 *
 *  The `ERC721LazyMint` smart contract implements the ERC721 NFT standard, along with the ERC721A optimization to the standard.
 *  It includes the following additions to standard ERC721 logic:
 *
 *      - Lazy minting
 *
 *      - Contract metadata for royalty support on platforms such as OpenSea that use
 *        off-chain information to distribute roaylties.
 *
 *      - Ownership of the contract, with the ability to restrict certain functions to
 *        only be called by the contract's owner.
 *
 *      - Multicall capability to perform multiple actions atomically
 *
 *      - EIP 2981 compliance for royalty support on NFT marketplaces.
 *
 *  'Lazy minting' means defining the metadata of NFTs without minting it to an address. Regular 'minting'
 *  of  NFTs means actually assigning an owner to an NFT.
 *
 *  As a contract admin, this lets you prepare the metadata for NFTs that will be minted by an external party,
 *  without paying the gas cost for actually minting the NFTs.
