Function Synopsis

rv1=colormesh2d(fem_grid_struct,Q,nband)

Help text

COLORMESH2D draw a FEM mesh in 2-d colored by a scalar quantity.

   INPUT : fem_grid_struct (from LOADGRID, see FEM_GRID_STRUCT)
	    Q	      - scalar to color with (optional)
	    nband     - number of contour bands to compute (optional)

	    With no scalar specified to contour, COLORMESH2D
	    defaults to the bathymetry fem_grid_struct.z

  OUTPUT : hp - vector of handles, one for each element patch drawn.

   COLORMESH2D colors the mesh using the scalar Q.  If Q
   is omitted from the argument list, COLORMESH2D draws
   the element connectivity in black and white.

 NOTE: This is one of the few (2 or 3) OPNML MATLAB functions that 
       deletes existing patch objects in  the current axes before 
       rendering the surface.  This is to avoid having an unmanageable 
       number of patch objects on the screen.  

   CALL : >> hp=colormesh2d(fem_grid_struct,Q,nband)
