Class
    Foam::PhiScheme

Description
    Class to create the weighting-factors based on the face-flux.

    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 with the central-differencing weighting factor, the face-flux,
    the face neighbour cell values and the face area.

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