Title: Fix trigcoeffs

I was under the impression that coeffs were ordered the right way in ```@trigtech``` but this was not the case. The coefficients of a ```trigtech``` were being stored with the positive modes on top and the negative ones below. I have changed this so that we now have negative modes on top and positive at the bottom at _all_ levels.
