contains-other-v no longer implies delete-other-v

Deletion of other vertices is now only determined by the delete-other-v
property. For containment relationships, this property is now explicitly
set instead of being implied by the containment property. ie Deletion
now
only checks delete-other-v not containment, and containment
relationships
have been updated to still function the same as before.
