Get sets of tokens (TokenBins) that have been paired across the two functions.
The pairing can be performed either forcing constants to match, or not.
@param matchConstantsExactly is true if constants should be forced to match
@param monitor is the TaskMonitor
@return the list of TokenBins
@throws CancelledException if the user cancels the task
