public class PowerSet<T>
extends Object

In mathematics, the power set (or powerset) of any set S, written P(S), is the set of all subsets of S, including the empty set and S itself.

Code taken from StackOverflow best answer in: http://stackoverflow.com/questions/4640034/calculating-all-of-the-subsets -of-a-set-of-numbers. HashSet changed to LinkedHashSet for the consistent order of the subsets and easier testing.

Currently used to calculate the possible LOCAL symmetries in QuatSymmetryDetector.
