Wraps an integer to be used with the range-based for construct.
Not really an iterator, rather a pseudo-index. Geogram mostly uses index-based data structures, where an element is an index in an array (whereas the STL uses pointer-like semantics). With indices, there is no indirection (an index is an element), so operator* does nothing (returns the stored index).
