    IMPORTANT DESIGN DOCUMENTATION
    This is a start towards influencing the contents of the image functor
    rulebase on a per instantiation basis. The arguments passed to the
    constructor currently have default values to ensure backward compatibality.
    Jan-Mark will have an example instantiation to show a possible application
    of a non default value.
