+	Description:	Old script when I was trying to make propagation to off-axis parabolic mirrors
+					work in 3D. This was based on papers by Matsushima (around 2004, I believe).
+					This was about as far as I got with this. Here I also plot a 3D wireframe to
+					inspect the physical geometry that I'm trying to simulate.
+
+					The end goal of having this propagation code on rotated surfaces work:
+					- Model the full 3D optical model of MICADO, including off-axis parabolas!
+					  Likely, the off-axis parabola's would be modelled as flat mirrors, but
+					  again with a phase transformation to provide the wavefront curvature.
+					  
+					If you get this to work, please do let me know!
