Defines a lexicographical order for pairs\&.

For two pairs of the same type, \fRP\fP is ordered before \fRQ\fP if \fRP\&.first\fP is less than \fRQ\&.first\fP, or if \fRP\&.first\fP and \fRQ\&.first\fP are equivalent (neither is less than the other) and \fRP\&.second\fP is less than \fRQ\&.second\fP\&.
