findCommonContainingGroup method
Find the Group that perhaps indirectly contains both this part and another one. If this is a Group and it contains the OTHER Part, return this. If the OTHER Part is a Group and it contains this Part, return that OTHER Part.
This returns null if the two parts are unrelated in the hierarchy of part membership. If non-null, the result is a Group.
If you want to find the Node that is the tree parent of two Nodes, call Node#findCommonTreeParent. @param {Part} other @return {Group} may be null
