Class
    Foam::boundaryRegion

Description
    The boundaryRegion persistent data saved as a Map<dictionary>.

    The meshReader supports boundaryRegion information.

    The <tt>constant/boundaryRegion</tt> file is an @c IOMap<dictionary>
    that is used to save the information persistently.
    It contains the boundaryRegion information of the following form:

    @verbatim
        (
            INT
            {
                BoundaryType    WORD;
                Label           WORD;
            }
            ...
        )
    @endverbatim
