ELLIPSE plot ellipse given center, major/minor axes, orientation, etc. 
 ELLIPSE plot ellipse given center, major and minor axes, 
         orientation, and color (optional, def = 'r')

  Input : xc    - ellipse x-coordinate centers, usually node x's;
          yc    - ellipse y-coordinate centers, usually node y's;
          umaj  - major axis component
          umin  - minor axis component
          orien - orientation clockwise from north (radians)
          col   - color to draw ellipses (optional, def = 'r')
 
          ELLIPSE plots ellipses centered at (xc,yc) with major
          and minor axes (umaj,umin) at an orientation 
          (orien) radians clockwise from north.  The first
          five arguments are required; the color (col) is not and
          defaults to red.

  Output: ELLIPSE returns the handle to the ellipse object drawn.
            
 Call as: hell=ellipse(xc,yc,umaj,umin,orien,col)
