I have corrected the Quicksort pivot check and added more comprehensive checks that particles are sorted in the right cells and not just sorted in the right order.

But.... I have done this in the star_particles branch: 601b7d0e...7de859fb

since the same fix had to be applied to all 3 particle types. That makes it harder for you to test I realize now.

I'll accept this request so we can rationalise the approach to more testing. We need to open an issue to look at when to sort these particles (before sending), so we can get back the performance.
