ERC-721 Lazy Mint

The ERC721LazyMint smart contract uses the ERC721Base base contract along with the LazyMint contract extension.

'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.
