~Roo2DKeysPdf()

     Load a new data set into the class instance.  If the calculation fails,
        return 1
        return 0 indicates a success

     use the cacheing intrinsic in RFC to bypass the grid and remove
     the grid and extrapolation approximation in the kernel estimation method
    implementation - cheers Wouter :)
