Always consider card of includes type constraints
Always consider card of includes type constraints

Previously, we only considered the card of an "includes type" constraint if it was accompanied by a "slice at" command.  This was incorrect, as "includes type" can also happen without a "slice at" command, and should still affect the calculated cardinality.

Partly fixes #72.
