huey: Internal maintenance specification

The polite way to implement a virtual method in Python (like this one) is to raise the NotImplementedError exception. For the interface, see Section 7, “class ColorModel: Base class for color models”.

# - - -   C o l o r M o d e l . p a r a m s T o C o l o r

    def paramsToColor ( self, params ):
        raise NotImplementedError, "ColorModel.paramsToColor"
