## Description

    A simple rectangular or circular slit. You may either
    specify the radius (circular shape), or the rectangular bounds.
    No transmission around the slit is allowed.
    If cutting option is used, low-weight neutron rays are ABSORBED

    Example: Slit(xmin=-0.01, xmax=0.01, ymin=-0.01, ymax=0.01)
             Slit(radius=0.01, cut=1e-10)

## Input parameters

Parameters in boldface are required; the others are optional.

Name | Unit | Description | Default
--- | --- | --- | ---
xmin | m | Lower x bound | 0
xmax | m | Upper x bound | 0
ymin | m | Lower y bound | 0
ymax | m | Upper y bound | 0
radius | m | Radius of slit in the z=0 plane, centered at Origo | 0
cut | 1 | Lower limit for allowed weight | 0
