Subject: [PATCH] In Occurrence_Contains(), accept everything when _instance is
 NULL.

* Bug: In Hurricane::Occurrence_Contains(), when the Instance to match
    is set to NULL, that means we have to accept *all* instances instead
    of rejecting them all. This bug was making the Cell::flattenedNets()
    to do nothing in digital mode.
