Smart Contract NFTs

In order to integrate NFTs into a game, we need a smart contract for the NFTs. We'll create an NFT project locally, edit the NFT smart contract, fund the testnet account with STX and upload it there. The clarinet project should be created in the root folder of the cloned repository.
