Iterator class for sparse vector-like containers.
This class provides an iterator for sparse vector like containers. It contains a ContainerWrapper that must provide the translation from the position in the underlying container to the index in the sparse container.
The ContainerWrapper must be default and copy-constructable. Furthermore it must provide the methods:
bool identical(other) - check if this is identical to other (same container, not only equal) T* pointer(position) - get pointer to data at position in underlying container size_t realIndex(position) - get index in sparse container for position in underlying container
Notice that the iterator stores a ContainerWrapper. This allows one to use proxy classes as underlying container and as returned reference type.
