GhostingFunctor subclasses with relatively long-lasting caches may want to redistribute those caches whenever the relevant Mesh is redistributed; we will give them an opportunity when that happens.
At the point in the code where this is called, element processor ids have been set to their new destinations, and those elements have been copied to their new destinations, but the elements have not yet been deleted by the processors which previously held them..

Constructor.
Constructor. A clone() is needed because GhostingFunctor can not be shared between different meshes. The operations in GhostingFunctor are mesh dependent. If we have periodic boundaries, then we'll need the mesh to have an updated point locator whenever we're about to query them.
