Class
    Foam::pimpleSingleRegionControl

Description
    Pimple single region control class. Provides time-loop control methods
    which exit the simulation once convergence criteria have been reached. Also
    provides Pimple-loop control methods which exit the iteration once corrector
    convergence criteria have been met. Example usage:

    \verbatim
    pimpleSingleRegionControl pimple(mesh);

    while (pimple.run(runTime))
    {
        // pre-time-increment operations ...

        runTime ++;
        Info<< "Time = " << runTime.userTimeName() << nl << endl;

        while (pimple.loop())
        {
            // solve ...
        }

        // post-solve operations ...
    }
    \endverbatim
