accrueFee()

function accrueFee(ISetToken _setToken)Calculates total inflation percentage then mints new Sets to the fee recipient. Position units are then adjusted down (in magnitude) in order to ensure full collateralization. Callable by anyone.

Parameter Name	Type	Description
_setToken	ISetToken	Instance of the SetToken

initialize()

function initialize(ISetToken _setToken, FeeState memory _settings)Manager only. Initializes this module to the SetToken.

Parameter Name	Type	Description
_setToken	ISetToken	Address of the SetToken
_settings	FeeState	FeeState struct defining fee parameters

The FeeState struct is constructed as follows:

struct FeeState {
    address feeRecipient;                   // Address to accrue fees to
    uint256 maxStreamingFeePercentage;      // Max streaming fee maanager commits to using (1% = 1e16, 100% = 1e18)
    uint256 streamingFeePercentage;         // Percent of Set accruing to manager annually (1% = 1e16, 100% = 1e18)
    uint256 lastStreamingFeeTimestamp;      // Timestamp last streaming fee was accrued
}                                                  

updateStreamingFee()

function updateStreamingFee(ISetToken _setToken, uint256 _newFee)Manager only. Set new streaming fee. Fees accrue at current rate then new rate is set. Fees are accrued to prevent the manager from unfairly accruing a larger percentage.

Parameter Name	Type	Description
_setToken	address	Instance of the SetToken
_newFee	uint256	New streaming fee in 18 decimal precision

updateFeeRecipient()

function updateFeeRecipient(ISetToken _setToken, address _newFeeRecipient)Manager only. Set new fee recipient.
