This class wraps zones for delegation.

When forwarding to parent zones one can't just invoke the parent zone's exposed functions (like, but one needs to provide more information (like the zone the run was initiated). Zone callbacks thus receive more information including this ZoneDelegate class. When delegating to the parent zone one should go through the given instance instead of directly invoking the parent zone.
