DRAWCIRCLEARC Draw a circle arc on the current axis.

   drawCircleArc(ARC);
   Draws circle arc defined by ARC = [XC YC R START EXTENT], with (XC, YC)
   being the circle center, R being the circle radius, starting from angle 
   START, and with angular extent given by EXTENT. START and EXTENT angles
   are given in degrees.

   drawCircleArc(XC, YC, R, START, EXTENT);
   Alternative syntax that seperates inputs.

   drawCircleArc(..., PARAM, VALUE);
   specifies plot properties by using one or several parameter name-value
   pairs.

   drawCircleArc(AX, ...);
   Specifies handle of the axis to draw on.

   H = drawCircleArc(...);
   Returns a handle to the created line object.

   Example
     % Draw a red thick circle arc
     arc = [10 20 30 -120 240];
     figure;
     axis([-50 100 -50 100]);
     hold on
     drawCircleArc(arc, 'LineWidth', 3, 'Color', 'r')
