* The `ERC721Base` smart contract implements the ERC721 NFT standard, along with the ERC721A optimization to the standard.
* It includes the following additions to standard ERC721 logic:
*
* - Ability to mint NFTs via the provided `mint` function.
*
* - Contract metadata for royalty support on platforms such as OpenSea that use
* off-chain information to distribute roaylties.
*
* - Ownership of the contract, with the ability to restrict certain functions to
* only be called by the contract's owner.
*
* - Multicall capability to perform multiple actions atomically
*
* - EIP 2981 compliance for royalty support on NFT marketplaces.
