FDVECTOR plot vectors from a bfd sampling.
   FDVECTOR plots vectors from a FEM domain that has been
   sampled on a finite difference grid.  The FD grid
   is contained in a .bfd file (See GENBFD) and FDVECTOR
   handles the interpolatopn of FE vector data onto
   the FD grid.  (VECPLOT2 does the actual plotting.)

   Input:   bdf    - bfd array (all 10 columns)
            u      - east vector amplitude
            v      - west vector amplitude
            sc     - vector scaler; (optional; def = 1.)
            stride - stride over nodes
            sclab  - label for vector scale; (optional; def = 'cm/s')
            scale_xor,scale_yor - vector scale origin (optional)

   The stride argument is used to plot every other 
   vector (stride=2, e.g.).

   Including the scale_xor,scale_yor prevents the mouse-driven 
   specification of the vector scale placement.
 
   Output: h - vector of handles to objects drawn.
