Inherits:Error
Authors: Instadapp, Modified Solmate (https://github.com/transmissions11/solmate/blob/main/src/tokens/ERC721.sol)
Fluid Vault Factory ERC721 base contract. Implements the ERC721 standard, based on Solmate. In addition, implements ERC721 Enumerable. Modern, minimalist, and gas efficient ERC-721 with Enumerable implementation.
