/**
 * @notice IncentiveMatcher contract corresponds to a ve token and manages
 * incentive matching for incentives related to that ve token.  This contract
 * allows protocols to provide matching incentives to Maverick Boosted
 * Positions (BPs) and allows ve holders to vote their token to increase the
 * match in a BP.
 *
 * IncentiveMatcher has a concept of a matching epoch and the following actors:
 *
 * - BP incentive adder
 * - Matching budget adder
 * - Voter
 *
 * @notice The lifecycle of an epoch is as follows:
 *
 * - Anytime before or during an epoch, any party can permissionlessly add a
 * matching and/or voting incentive budget to an epoch.  These incentives will
 * boost incentives added to any BPs during the epoch.
 * - During the epoch any party can permissionlessly add incentives to BPs.
 * These incentives are eligible to be boosted through matching and voting.
 * - During the voting portion of the epoch, any ve holder can cast their ve
 * vote for eligible BPs.
 * - At the end of the epoch, there is a vetoing period where any user who
 * provided matching incentive budget can choose to veto a BP from being
 * matched by their portion of the matching budget.
 * - At the end of the vetoing period, the matching rewards are eligible for
 * distribution.  Any user can permissionlessly call `distribute` for a given
 * BP and epoch.  This call will compute the matching boost for the BP and then
 * send the BP reward contract the matching amount, which will in turn
 * distribute the reward to the BP LPs.

/**
 * @dev Interface of the ERC20 Permit extension allowing approvals to be made via signatures, as defined in
 * https://eips.ethereum.org/EIPS/eip-2612[EIP-2612].
 *
 * 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 {}
 *     doThing(..., value);
 * }
 *
 * function doThing(..., uint256 value) public {
 *     token.safeTransferFrom(msg.sender, address(this), value);
 *     ...
 * }
 * ```
 *
 * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of
 * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also
 * {SafeERC20-safeTransferFrom}).
 *
 * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so
 * contracts should have entry points that don't rely on permit.
