Description

Based on Pol_guide_vmirror by P. Christiansen.
Models a rectangular guide with entrance centered on the Z axis and
with one supermirros sitting on the diagonal inside.
The entrance lies in the X-Y plane.  Draws a true depiction
of the guide with mirror and trajectories.
The polarisation is handled similar to in Monochromator_pol.
The reflec functions are handled similar to Pol_mirror.
The up direction is hardcoded to be along the y-axis (0, 1, 0)

Note that this component can also be used as a frame overlap-mirror
if the up and down reflectivities are set equal. In this case the wall
refletivity (rPar) should probably be set to absorb.

The parameters can either be
double pointer initializations (e.g. {R0, Qc, alpha, m, W})
or table names (e.g."supermirror_m2.rfl" AND useTables=1).
NB! This might cause warnings by the compiler that can be ignored.

GRAVITY: YES

%BUGS
No absorption by mirror.
