-""" There is some shared logic between matching/multiplying inputs in workflows
-and tools. This module is meant to capture some general permutation logic that
-can be applicable for both cases but will only be used in the newer tools case
-first.
-
-Maybe this doesn't make sense and maybe much of this stuff could be replaced
-with itertools product and permutations. These are open questions.
