+   * Code Popcorn Plug-in
+   *
+   * Adds the ability to run arbitrary code (JavaScript functions) according to video timing.
+   *
+   * @param {Object} options
+   *
+   * Required parameters: start, end, template, data, and target.
+   * Optional parameter: static.
+   *
+   *   start: the time in seconds when the mustache template should be rendered
+   *          in the target div.
+   *
+   *   end: the time in seconds when the rendered mustache template should be
+   *        removed from the target div.
+   *
+   *   onStart: the function to be run when the start time is reached.
+   *
+   *   onFrame: [optional] a function to be run on each paint call
+   *            (e.g., called ~60 times per second) between the start and end times.
+   *
+   *   onEnd: [optional] a function to be run when the end time is reached.
+   *
+   * Example:
+     var p = Popcorn('#video')
+
+        // onStart function only
+        .code({
+          start: 1,
+          end: 4,
+          onStart: function( options ) {
+            // called on start
+          }
+        })
+
+        // onStart + onEnd only
+        .code({
+          start: 6,
+          end: 8,
+          onStart: function( options ) {
+            // called on start
+          },
+          onEnd: function ( options ) {
+            // called on end
+          }
+        })
+
+        // onStart, onEnd, onFrame
+        .code({
+          start: 10,
+          end: 14,
+          onStart: function( options ) {
+            // called on start
+          },
+          onFrame: function ( options ) {
+            // called on every paint frame between start and end.
+            // uses mozRequestAnimationFrame, webkitRequestAnimationFrame,
+            // or setTimeout with 16ms window.
+          },
+          onEnd: function ( options ) {
+            // called on end
