How about some unit tests?

> There are many uses cases for setting bits flags and being able filter on those seems like a good idea.
> The BitComparator would take a byte[] and a bitwise operator for its constructor. It would perform the bitwise operation on the column value bytes with the specified byte[]. Then return whether the result was non-zero. 
> Only the CompareOp.EQUAL and CompareOp.NOT_EQUAL would make sense with this comparator.
> The binary bitwise operators that apply  are AND, OR, and XOR.
