PDD [PandaDAO Finance] Token

PandaDAOFinanceToken._tFeeTotal (PandaDAOFinanceToken.sol#34) is never initialized. It is used in:
- PandaDAOFinanceToken.totalFees() (PandaDAOFinanceToken.sol#144-146)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.
