171
* 3. The open content is shown and the closed content is closed.
173
* 4. The animation to expose all of the open content is started.
175
* 5. If we have to do ajax to load content, start the request.
177
* 6. When the request completes, parse the content into a node, run
178
* the node_process callback over it and replace the spinner (assumed
179
* to be appropriately contained in the open node) with the new node.
181
* 7. If the animation showing the open content has not completed,
184
* 8. Start a new animation to show the rest of the new content.
