+   *
+   *   * `setup`: `function(Element):*` A function which receives the starting state of the element. The purpose
+   *   of this function is to get the element ready for animation. Optionally the function returns an memento which
+   *   is passed to the `start` function.
+   *   * `start`: `function(Element, doneFunction, *)` The element to animate, the `doneFunction` to be called on
+   *   element animation completion, and an optional memento from the `setup` function.
+   *
+   * @param {string} name The name of the animation.
+   * @param {function} factory The factory function that will be executed to return the animation object.
