DOCUMENT plc_label, z,y,x, levs, ndivs=ndivs, opaque=opaque, lmgrid=lmgrid

  call after plc,z,y,x in order to put labels on an existing contour
  plot.  If you are going to set the limits (by means of the limits
  or range functions, or zooming or panning with the mouse), do so
  before calling plc_label, since it reads the current plot limits.

  finds points where numeric contours labels can be drawn 
  input

   y: y coords of array to be contoured

   ndivs: divide domain into ndvis x ndivs subregions with label in each
   opaque: if defined, white out below label
