This project implements the ERC721 Non-Fungible Token Standard, including the Metadata, Enumerable and Ownable extensions, and include a mint function to mint from a list of IPFS hashes (CIDs) that link to the json metadata.

Additional and extended functions
- mint(): Mints the specified list of
hashes(the IPFS hash of the metadata file) on behalf ofto. - walletOfOwner(): Returns the tokenIds of the
owner. - tokenURI(): Returns the Uniform Resource Identifier (URI) for the
tokenIdwith the IPFS hash of the json metadata file. - setBaseURI(): Changes the actual {baseURI} to the
newBaseURI.
