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 {
