func (*FeeManager) CalcFixedFee 

func (m *FeeManager) CalcFixedFee(balances sdk.Coins, eventType transferEventType, inAsset string, engines map[string]*matcheng.MatchEng) sdk.Fee

Note: the result of `CalcFixedFee` depends on the balances of the acc, so the right way of allocation is: 1. transfer the "inAsset" to the balance, i.e. call doTransfer() 2. call this method 3. deduct the fee right away

func (m *FeeManager) CalcTradeFee(balances sdk.Coins, tradeIn sdk.Coin, engines map[string]*matcheng.MatchEng) sdk.Fee

DEPRECATED Note1: the result of `CalcTradeFeeDeprecated` depends on the balances of the acc, so the right way of allocation is: 1. transfer the "inAsset" to the balance, i.e. call doTransfer() 2. call this method 3. deduct the fee right away

Note2: even though the function is called in multiple threads, `engines` map would stay the same as no other function may change it in fee calculation stage, so no race condition concern
