There are two key additions for all weight computation methods in this PR.
If nOverlapFaces=0, skip computation all together as this means that we are dealing with a ghost element in MOAB and hence no intersection mesh is defined in that region (intentional)
If an overlap element does not have a parent target element defined, skip assembly as needed. This has a similar motivation as well for parallel MOAB weight computation
