/**

 * @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 a proxied contract can't have 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.

 *

 * 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]

 * ====

 * Avoid leaving a contract uninitialized.

 *

 * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation

 * contract, which may impact the proxy. To initialize the implementation contract, you can either invoke the

 * initializer manually, or you can include a constructor to automatically mark it as initialized when it is deployed:
