superficial part (superficialPart)

(superficialPart obj1 obj2) means that obj1 is a part of obj2 that has no interior parts of its own (or, intuitively, that only overlaps those parts of obj2 that are externally connected with the mereological complement of obj2). This too is a transitive relation closed under MereologicalSumFn and MereologicalProductFn.
