Class
    Foam::LimitedScheme

Description
    Class to create NVD/TVD limited weighting-factors.

    The particular differencing scheme class is supplied as a template
    argument, the weight function of which is called by the weight function
    of this class for the internal faces as well as faces of coupled
    patches (e.g. processor-processor patches). The weight function is
    supplied the central-differencing weighting factor, the face-flux, the
    cell and face gradients (from which the normalised variable
    distribution may be created) and the cell centre distance.

    This code organisation is both neat and efficient, allowing for
    convenient implementation of new schemes to run on parallelised cases.
