Bug in parabola bottom about freepaths HOT 3 CLOSED

The images with red lines through the structures are directional phonon sources. These are focussing cases. The other ones are collimating cases where the phonons are generated in the focus of the parabola

I checked, yes, apparently the bottom parabola works when used to collimate (that's why we never noticed before) but fails when used to focus. In fact, the scattering code for top and bottom parabola is the same, which is probably wrong. I'll need to check it more seriously. But since now we can launch phonons from any side, maybe one working parabola is enough 😆

Looks like I fixed it, although I didn't test extensively.


So, I'll close it for now.
