AirshipSim:
--------------------------------------------------------------------------
Simulate an airship in flight

Inputs
------
d (.) Aircraft data structure
x (:) Initial state, class "acstate"
T (1) Length of simulation (sec)
dT (1) Optional. Time step (sec). Default is 0.1 sec.
control (.) Optional. Control input data structure with
following fields, where integer N > T/dT.
- throttle (1,N) Throttle command (0-1)
- mu (1,N) Thrust vector angle
