Swapping Lock Coordinates

A motion tracking setup had two trackers assigned incorrectly; they needed to be swapped.

define the procedure to swap the lock position of a tracker and a tracker.

find the first tracker's lock position.

make the first tracker's lock position the second tracker's lock position.

make the second tracker's lock position the vector from step 1. done.

Now you can

swap the lock position of tracker 3 and tracker 7.

This can easily be modified to swap any attributes, but really this is a good candidate for a general built-in rule of its own.
