  $Log: VectorArray.c,v $
  Revision 1.2  1996/04/30 18:53:38  wenger
  Attrproj now generates a single projection of all attributes of the
  real data.

  Revision 1.1  1996/04/30 15:31:55  wenger
  Attrproj code now reads records via TData object; interface to Birch
  code now in place (but not fully functional).
