20050226 exercise: generate all possible pairings
given a list that is a set partitioned into subsets, generate a list
of all possible pairings of elements in any two subset.
Example:
genpair( [[9,1],[5],[2,8,7]] );
returns:
[[5,8],[9,5],[1,5],[9,2],[9,7],[1,8],[1,7],[5,2],[1,2],[9,8],[5,7]]
(we do not assume the given set has order, so the result is not
ordered.)
Perl code and Python code will be posted in 2 days.
