/**
* 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.
