Class
    Foam::processorLODs::faceBox
 
Description
    Creates the parallel distribution map by describing the source and target
    objects using box shapes.
 
    A single box is created for the source object, which is then split using
    2x2x2 refinement based on the number of remote target objects that overlap.
    The refinement is local between communicating processor pairs, where the
    refinement continues until a threshold number of remote target objects per
    source box is achieved.
