% Aerodynamic model for a CubeSat.
Contains a built-in demo for a 1U CubeSat in a 6500 km orbit.
Also contains an option to retrieve the default data structure.
Note that it is most efficient to combine the areas into one per face
for simple CubeSat models - i.e. 6 areas.
The attitude model in CubeSatAttitude will be used if p.q is empty.

Form:
[force, torque] = CubeSatAero( p, d )
d = CubeSatAero % data structure
