ArrayPatch:

--------------------------------------------------------------------------
   Create solar array models.
   Two are created, one for the front and
   one for the back. The array is nominally in the xz-plane. 
   Its center is at x = 0 and it goes from z = 0 to z = length. The
   cell face normal is +Y.
--------------------------------------------------------------------------
   Form:
   [mFront, mBack] = ArrayPatch( d )

   Inputs
   ------
   d                 Data structure
                     d.nZ          Number of segments along z
                     d.nX          Number of segments along x
                     d.z           Dimension of each panel in z
                     d.x           Dimension of each panel in x
                     d.theta(d.nX) Angle between panels along z. Sign determines
                                   the sign of the first panel.
                                   One element is required for each nX
                                   If omitted will be set to zero.
                     d.accordion   If true don't alternate angles
                     d.dirZ        If entered gives the direction for z

   Outputs

   mFront            struct( 'v', 'f' )
   mBack             struct( 'v', 'f' )
