    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  
 z  : array to be contoured  
 y: y coords of array to be contoured  
 x: x coords of array to be contoured  
 levs: contour levels to be labelled  
 ndivs: divide domain into ndvis x ndivs subregions with label in each  
 opaque: if defined, white out below label  
 lmgrid: if defined, draw the subregion perimeters
