+/**
+ * @file
+ * Javascript required for a simple collapsible div.
+ *
+ * Creating a collapsible div with this doesn't take too much. There are
+ * three classes necessary:
+ *
+ * - ctools-collapsible-container: This is the overall container that will be
+ *   collapsible. This must be a div.
+ * - ctools-collapsible-handle: This is the title area, and is what will be
+ *   visible when it is collapsed. This can be any block element, such as div
+ *   or h2.
+ * - ctools-collapsible-content: This is the ocntent area and will only be
+ *   visible when expanded. This must be a div.
+ *
+ * Adding 'ctools-collapsible-remember' to the container class will cause the
+ * state of the container to be stored in a cookie, and remembered from page
+ * load to page load. This will only work if the container has a unique ID, so
+ * very carefully add IDs to your containers.
+ *
+ * If the class 'ctools-no-container' is placed on the container, the container
+ * will be the handle. The content will be found by appending '-content' to the
+ * id of the handle. The ctools-collapsible-handle and
+ * ctools-collapsible-content classes will not be required in that case, and no
+ * restrictions on what of data the container is are placed. Like
+ * ctools-collapsible-remember this requires an id to eist.
+ *
+ * The content will be 'open' unless the container class has 'ctools-collapsed'
+ * as a class, which will cause the container to draw collapsed.
