Class
    Foam::refinementIterator
 
Description
    Utility class to do iterating meshCutter until all requests satisfied.
 
    Needed since cell cutting can only cut cell once in one go so if
    refinement pattern is not compatible on a cell by cell basis it will
    refuse to cut.
 
    Parallel: communicates. All decisions done on 'reduce'd variable.
