* @dev Implementation of the {IERC20} interface.

*
* 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}.

/**
* @title Token Deposit Box
* @notice This is a minimal example of a financial template that depends on price requests from the DVM.
* This contract should be thought of as a "Deposit Box" into which the user deposits some ERC20 collateral.
* The main feature of this box is that the user can withdraw their ERC20 corresponding to a desired USD amount.
* When the user wants to make a withdrawal, a price request is enqueued with the UMA DVM.
* For simplicty, the user is constrained to have one outstanding withdrawal request at any given time.
* Regular fees are charged on the collateral in the deposit box throughout the lifetime of the deposit box,
* and final fees are charged on each price request.
*
* This example is intended to accompany a technical tutorial for how to integrate the DVM into a project.
* The main feature this demo serves to showcase is how to build a financial product on-chain that "pulls" price
* requests from the DVM on-demand, which is an implementation of the "priceless" oracle framework.
*
* The typical user flow would be:
* - User sets up a deposit box for the (wETH - USD) price-identifier. The "collateral currency" in this deposit
* box is therefore wETH.
* The user can subsequently make withdrawal requests for USD-denominated amounts of wETH.
* - User deposits 10 wETH into their deposit box.
* - User later requests to withdraw $100 USD of wETH.
* - DepositBox asks DVM for latest wETH/USD exchange rate.
* - DVM resolves the exchange rate at: 1 wETH is worth 200 USD.
* - DepositBox transfers 0.5 wETH to user.

* @title Liquidatable
* @notice Adds logic to a position-managing contract that enables callers to liquidate an undercollateralized position.
* @dev The liquidation has a liveness period before expiring successfully, during which someone can "dispute" the
* liquidation, which sends a price request to the relevant Oracle to settle the final collateralization ratio based on
* a DVM price. The contract enforces dispute rewards in order to incentivize disputers to correctly dispute false
* liquidations and compensate position sponsors who had their position incorrectly liquidated. Importantly, a
* prospective disputer must deposit a dispute bond that they can lose in the case of an unsuccessful dispute.
* NOTE: this contract does _not_ work with ERC777 collateral currencies or any others that call into the receiver on
* transfer(). Using an ERC777 token would allow a user to maliciously grief other participants (while also losing
* money themselves).
