DrawSpacecraftPatches:

--------------------------------------------------------------------------
   Draw the spacecraft CAD model using patches.
   Handles truss or line components. The model can be scaled up or 
   exploded by passing in the appropriate factor.

   Type DrawSpacecraftPatches for demo.

   Form:
   [h, vMinS, vMaxS] = DrawSpacecraftPatches( hAxis, g, B0, r0, 
                                     ambientStrength, scale, explode  )
   DrawSpacecraftPatches( h, g, [], [], ambientStrength, scale, explode  )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   hAxis (1,1)  or (:)  Handle to the axes, or the the patches for a redraw
   g         (.)      CAD model
   B0       (3,3)     Rotation matrix
   r0       (3,1)     Initial position
   ambientStrength (1,1) Ambient light strength
   scale    (1,1)      Scale, default 1
   explode  (1,1)      Explode factor, default 1

   -------
   Outputs
   -------
   h         (:)      Handles to the patch objects
   vMinS     (3)      Minimum limits on axes
   vMaxS     (3)      Maximum limits on axes
