Class
    Foam::fv::fvCellSet

Description
    Cell-set fvConstraint abstract base class. Provides a base set of controls
    regarding the location where the fvConstraint is applied.

Usage
    Example usage:
    \verbatim
    constraint1
    {
        type            <constraintType>

        // Apply everywhere
        selectionMode   all;

        // // Apply within a given cell set
        // selectionMode   cellSet;
        // cellSet         c0;

        // // Apply in cells containing a list of points
        // selectionMode   points;
        // points
        // (
        //     (2.25 0.5 0)
        //     (2.75 0.5 0)
        // );

        ...
    }
    \endverbatim
