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)
