Usage

There are two addtional functions to this ERC721 that can be called.

The setMinter function call only be called by the owner (deployer) of this contract. With that it is possible to whitelist new address that can mint new NFTs and also set a limit how many NFTs they can mint.

The mint function can be called (by an address) to actually mint the NFT as long as that address is whitelisted and below its token allowance.
