## Description

    Sample for Small Angle Neutron Scattering.
    Modified from the Any Sample model.
    Normalization of scattering is done in INITIALIZE.
    Some elements of Sans_spheres have been re-used

    Some remarks:
    Scattering function should be a defined the same way in INITIALIZE and TRACE sections
    There exist maybe better library functions for the integral.

    Transmitted paths set to 50% of all paths to be optimised for SESANS. In this simulation method paths are
    well distributed among transmission and scattering (equally in Q-space).

    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. Absorption is included to
    these sample-components.

    Example: SANS_Spheres_Abs(R=100, Phi=1e-3, Delta_rho=0.6, sigma_a = 50, qmax=0.03, xwidth=0.01, yheight=0.01, zthick=0.001)
