Models a rectangular curved guide tube with entrance centered on the Z axis.
The entrance lies in the X-Y plane. Draws a true depiction
of the guide, and trajectories. Guide is not focusing.
Example: Guide_curved(w1=0.1, h1=0.1, l=2.0, R0=0.99, Qc=0.021,
alpha=6.07, m=2, W=0.003, curvature=2700)
This component does not work with gravitation on. Use component Guide_gravity then.
Systematic error on transmitted flux is found to be about 10%.
WARNING: This is a contributed Component.
Parameters in boldface are required;
the others are optional.
Width at the guide entry

Critical scattering vector
Slope of reflectivity
m-value of material. Zero means completely absorbing.
