DBA [Digital Bank of Africa] Token

DBAToken._tBurnTotal (contracts/DBAToken.sol#33) is never initialized. It is used in:
- DBAToken._tTakeBurnFee(uint256) (contracts/DBAToken.sol#352-359)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.
