/**
 * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
 * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an
 * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
 * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
 *
 * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be
 * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in
 * case an upgrade adds a module that needs to be initialized.
 *
 * For example:
 *
 * [.hljs-theme-light.nopadding]
 * ```solidity
 * contract MyToken is ERC20Upgradeable {
 *     function initialize() initializer public {
 *         __ERC20_init("MyToken", "MTK");
 *     }
 * }
 *
 * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {
 *     function initializeV2() reinitializer(2) public {
 *         __ERC20Permit_init("MyToken");
 *     }
 * }
 * ```
 *
 * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
 * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
 *
 * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
 * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
 *
 * [CAUTION]

     * constructor.

* In Crossbell's operator system, every uint8 stands for a single method in Web3Entry.sol. <br>
* For most cases, we recommend simply granting operators the `OPERATOR_SIGN_PERMISSION_BITMAP`,
* which gives operator full permissions aside from owner permissions and future permissions, but for
* those who're more aware of access control, the custom permission bitmap is all yours,
* and you can find every customizable methods below. <br>
* `OPERATOR_SIGN_PERMISSION_BITMAP` have access to all methods in `OPERATOR_SYNC_PERMISSION_BITMAP`
* plus more permissions for signing. <br>
* Permissions are laid out in a increasing order of power.
* so the bitmap looks like this:
