> Iterating on RandomAccessSparseVector currently requires dumping all keys from the underlying OpenIntDoubleHashMap into a separate IntArrayList, then iterating over that and accessing the values.
> We should just make sure that OpenIntDoubleHashMap properly does iteration (instead of just allowing iteration callbacks a la forEachPair/forEachKey).
