* accounts that have a role's admin role can call {grantRole} and {revokeRole}.
*
* By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
* that only accounts with this role will be able to grant or revoke other
* roles. More complex role relationships can be created by using
* {_setRoleAdmin}.
*

* This implementation is agnostic to the way tokens are created. This means

*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How

*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}

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] ``` 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] ==== 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 prevent the implementation contract from being used, you should invoke the {_disableInitializers} function in the constructor to automatically lock it when it is deployed: [.hljs-theme-light.nopadding] ``` constructor() { _disableInitializers(); } ``` ====/ | abstract contract Initializable {
uint8 private _initialized;
bool private _initializing;
event Initialized(uint8 version);

bool isTopLevelCall = !_initializing;

(isTopLevelCall && _initialized < 1) ||

* @dev This is a base abstract contract that tracks voting units, which are a measure of voting power that can be
* transferred, and provides a system of vote delegation, where an account can delegate its voting units to a sort of
* "representative" that will pool delegated voting units from different accounts and can then use it to vote in
* decisions. In fact, voting units _must_ be delegated in order to count as actual votes, and an account has to
* delegate those votes to itself if it wishes to participate in decisions and does not have a trusted representative.
*
* This contract is often combined with a token contract such that voting units correspond to token units. For an
* example, see {ERC721Votes}.
*
* The full history of delegate votes is tracked on-chain so that governance protocols can consider votes as distributed
* at a particular block number to protect against flash loans and double voting. The opt-in delegate system makes the
* cost of this history tracking optional.
*
* When using this module the derived contract must implement {_getVotingUnits} (for example, make it return
* {ERC721-balanceOf}), and can use {_transferVotingUnits} to track a change in the distribution of those units (in the
* previous example, it would be included in {ERC721-_beforeTokenTransfer}).

/**
* @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 {UpgradeableProxy-constructor}.

* @dev Implementation of the {IERC20} interface.

* This implementation is agnostic to the way tokens are created. This means
* that a supply mechanism has to be added in a derived contract using {_mint}.
* For a generic mechanism see {ERC20PresetMinterPauser}.
*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.
