public SequenceIter<G> lookup_iter (G data, SequenceIterCompareFunc<G> iter_cmp)
Like lookup, but uses a SequenceIterCompareFunc instead of a CompareDataFunc as the compare function.
iter_cmp is called with two iterators pointing into this. It should return 0 if the
iterators are equal, a negative value if the first iterator comes before the second, and a positive value if the second iterator comes
before the first.
This function will fail if the data contained in the sequence is unsorted.
