    /**
    * @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");

    *
    * Adds the {permit} method, which can be used to change an account's ERC20 allowance (see {IERC20-allowance}) by
    * presenting a message signed by the account. By not relying on {IERC20-approve}, the token holder account doesn't
    * need to send a transaction, and thus is not required to hold Ether at all.
    *
    * ==== Security Considerations
    *
    * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature
    * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be
    * considered as an intention to spend the allowance in any specific way. The second is that because permits have
    * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should
    * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be
    * generally recommended is:
    *
    * ```solidity
    * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {
    * try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}
