<!--
`app-sk` provides general application layout, introducing a
responsive scaffold containing a header, toolbar, mtoolbar, rtoolbar, title and
areas for application content, as well as automatic inclusion of
common menu items, login status, and version tag.

Example:

    <app-sk mode="standard" responsive_width="600px" drawer_width="230px">
      <h1 header>Title goes here</h1>
      <div mtoolbar>middle stuff</div> <!- in the middle, between the title and rtoolbar ->
      <foo-status-sk rtoolbar></foo-status-sk> <!-to be right aligned, on the top bar ->
      <div navigation>Nav goes here</div>
      <div>Content goes here</div>
    </app-sk>

Properties:
  mode - Controls header and scrolling behavior for the paper-header-panel.
      Options are "standard", "seamed", "waterfall", "waterfall-tall", "scroll"
      and "cover". Default is "standard".

  tall_class - The class used by the paper-header-panel in waterfall-tall mode.
      Change this if the header accepts a different class for toggling height,
      e.g. "medium-tall"

  drawer_width - Width of the drawer panel, eg. "200px".

  force_narrow - Whether or not to force the paper-drawer-panel into narrow
      mode.

  narrow - Whether or not the paper-drawer-panel is currently in narrow mode.

  no_drawer - If true, no drawer panel is displayed at all.

  no_version - If true, no version element is displayed.

  responsive_width - Screen width at which the paper-drawer-panel switches into
      narrow mode.

  loginEle: The login-sk element in use by this element.

Methods:
  None.

Events:
  None.
