   * ~~~~~~~~~~
   *
   * This script makes the Sphinx sidebar collapsible.
   *
   * .sphinxsidebar contains .sphinxsidebarwrapper.  This script adds in
   * .sphixsidebar, after .sphinxsidebarwrapper, the #sidebarbutton used to
   * collapse and expand the sidebar.
   *
   * When the sidebar is collapsed the .sphinxsidebarwrapper is hidden and the
   * width of the sidebar and the margin-left of the document are decreased.
   * When the sidebar is expanded the opposite happens.  This script saves a
   * per-browser/per-session cookie used to remember the position of the sidebar
   * among the pages.  Once the browser is closed the cookie is deleted and the
   * position reset to the default (expanded).
