Info

There were two errors with calculations of the u_dot and u_dot_generalized

1. The moments generated by the aerodynamic surfaces was calculated relative to the instantaneous center of mass, instead of the center of dry mass
2. The inertias were being calculate relative tot the instatneous centero fmass, instead of relative tot he center of dry mass

The first error has been in the code since da91db9 aka the first ever commit!

Special thanks to @kevin-alcaniz for finding this
