class ResizingArrayBag[A] extends Bag[A]

Provides a bag (or multiset) of generic items, supporting insertion and iterating over the items in arbitrary order.

This implementation uses a resizing array. The add operation takes constant amortized time; the isEmpty, and size operations take constant time. Iteration takes time proportional to the number of items.
