New description:
Add a function that takes a perfect matching and returns the associated
fixed-point free involution.
Similarly, add a function that takes a perfect matching and returns the
associated set partition.
Lastly, change the string representation "_repr_" from PerfectMatching
[(1,2), (3,4)] to [(1,2), (3,4)].
