   Create an RWA Array. This is four wheels in a single box. The wheels
   are stuck on top of each other since the internal geometry is not
   defined.
---------------------------------------------------------------------------
   Form:
   m = RWAArray( model, cantAngle, wH, b, rA, body )
---------------------------------------------------------------------------

   -------
   Inputs

   d           (1,1)     RWA Data
   cantAngle   (1,1)     Cant angle from z
   wH          (1,2)     [width, height]
   b           (3,3)     Box orientation
   rA          (3,1)     Box location
   body        (1,1)     Body
