title: Using KineticJS to remove drawn objects
body: <p>Hopefully a simple question here:</p>
  
  <p>Say I've used KineticJS to draw a line as follows:</p>
  
  <pre><code>var redLine = new Kinetic.Line({
        points: [73, 70, 340, 23, 450, 60, 500, 20],
        stroke: "red",
        strokeWidth: 15,
        lineCap: "round",
        lineJoin: "round"
      });
  </code></pre>
  
  <p>And it's been added to a layer which has been added to the stage.</p>
  
  <p>But now I need to completely remove this line as if it was never there to react to some user event. How do I go about doing this?</p>
