This contract replaces those strict checks with slightly looser checks which\n * ensure that the SetToken remains collateralized after every transfer in/out for each component during issuance/redemption.\n * This module should be used to issue/redeem SetToken whose one or more components return a balance value with +/-1 wei error.\n * For example, this module can be used to issue/redeem SetTokens which has one or more aTokens as its components.\n * The new checks do NOT apply to any transfers that are part of an external position. A token that has rounding issues may lead to\n * reverts if it is included as an external position unless explicitly allowed in a module hook.\n \n The getRequiredComponentIssuanceUnits function on this module assumes that Default token balances will be synced on every issuance\n * and redemption. If token balances are not being synced it will over-estimate the amount of tokens required to issue a Set.\n /\ncontract DebtIssuanceModuleV2 is DebtIssuanceModule {\n using Position for uint256;\n\n / ============ Constructor ============ /\n\n constructor(IController _controller) public DebtIssuanceModule(_controller) {}\n\n / ============ External Functions ============ /\n\n /\n Deposits components to the SetToken, replicates any external module component positions and mints\n * the SetToken.
