The `Pol_guide_vmirror` Component

Polarising guide with two supermirros sitting in a v-shape inside.

Description

Models a rectangular guide with entrance centered on the Z axis and
with two supermirros sitting in a v-shape 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)

GRAVITY: YES
POLARISATION: YES

%BUGS 
No absorption by mirror.
