Description

Models a rectangular guide with entrance centered on the Z axis and
with nvs x two supermirrors sitting in v-shapes inside.
The entrance lies in the X-Y plane.  Draws a true depiction
of the guide with mirrors, 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)

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.
