* @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 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

*
* [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:
