Helper class that allows to use NCollection iterators as STL iterators. NCollection iterator can be extended to STL iterator of any category by adding necessary methods: STL forward iterator requires IsEqual method, STL bidirectional iterator requires Previous method, and STL random access iterator requires Offset and Differ methods.
