Bonk NFT Project.
A contract that plays around with ERC721 specification, and mints NFT Tokens free to a particular group of addresses added to the whitelist, while skipping those that aren't.
Addresses are added and removed from the whitelist in the Whitelist.sol contract. This gives them the priviledge of getting the NFT minted to them for free.
The minting or airdrop is done on the BonkNFT.sol contract.
