It is natural and more useful to let user simply specify exclude lists so they don't need to worry about patterns of other functions to be instrumented. This means that when only exclude list is specified, the default should be flipped to be true (instrument everything else). If there only include list, the default is false. If there are both, the include list should be used to specify a super set while the exclude list (taking precedence) used to specify a subset from the super set.
