## Description

    Debye-Scherrer Ring: Model for highly ordered diblock copolymer.
    This example is highly simple.
    Multiple scattering neglected, but could be incorporated.
    Sample that only produces a DebyeSherrer ring.
    Advantages:  Transmitted beam is simulated.
    Intensities still in flux units.
    Minor point: Absolute scattering probability given by transmission.

    Sample components leave the units of flux for the probability
    of the individual paths. That is more consitent than the
    Sans_spheres routine. Furthermore one can simulate the
    transmitted beam. This allows to determine the needed size of
    the beam stop. Only absorption has not been included yet to
    these sample-components. But thats really nothing.

    Example: SANS_DebyeS(transm=0.5, qDS=0.008, xwidth=0.01, yheight=0.01, zdepth=0.001)
