Class
    Foam::zoneDistribute
 
Description
    Class for parallel communication in a narrow band. It either provides a Map
    with the neighbouring values of the selected region or returns a Map of the
    required values in global addressing. Also holds a reference to the stencil
    Before the data transfer the communation has to be set up:
    exchangeFields_.setUpCommforZone(interfaceCell_);
    Is used in the plicRDF
