* @title OperatorFilterer
* @notice Abstract contract whose constructor automatically registers and optionally subscribes to or copies another
* registrant's entries in the OperatorFilterRegistry.
* @dev This smart contract is meant to be inherited by token contracts so they can use the following:
* - `onlyAllowedOperator` modifier for `transferFrom` and `safeTransferFrom` methods.
* - `onlyAllowedOperatorApproval` modifier for `approve` and `setApprovalForAll` methods.
* Please note that if your token contract does not provide an owner with EIP-173, it must provide
* administration methods on the contract itself to interact with the registry otherwise the subscription
* will be locked to the options set during construction.
