case classIndexedPowerSet[E](all: IndexedSeq[E]) extends Iterable[Set[E]] with Product with Serializable
A ℘ (IndexedPowerSet) constructed with a collection with elements of type E can construct
an Iterator which enumerates all possible subsets (of type Collection<E>) of the
collection used to construct the PowerSet.
