Using recursive loop to remove rows that match certain rules.

On each recursive iteration, Rule 1 is tested.

If a pair of rows match the rule, they are removed.
If no rows match rule 1, then Rule 2 is tested.
Again if a pair of rows match the rule they are removed.

If there is only 1 row remaining, the recursive loop ends.
If no rows were removed in the iteration the recursive loop ends.

This is then applied by a group loop to each group of rows.

See Forum post link for more details.
