/**
 *      BASE:      ERC1155Base
 *      EXTENSION: DropSinglePhase1155
 *
 *  The `ERC1155Base` smart contract implements the ERC1155 NFT standard.
 *  It includes the following additions to standard ERC1155 logic:
 *
 *      - 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.
 *
 *  The `drop` mechanism in the `DropSinglePhase1155` extension is a distribution mechanism for lazy minted tokens. It lets
 *  you set restrictions such as a price to charge, an allowlist etc. when an address atttempts to mint lazy minted tokens.
 *
 *  The `ERC721Drop` contract lets you lazy mint tokens, and distribute those lazy minted tokens via the drop mechanism.
