/* 
====================================================================
REQUIRED PAGE ELEMENTS:
====================================================================

--------------------------------------------------------------------
THE BREADCRUMB
--------------------------------------------------------------------
<div id="breadcrumbDIV"></div>
--------------------------------------------------------------------
- automatically inserts the breadcrumb trail with function gov_ShowBreadCrumbs();, called from the header javascript file.
--------------------------------------------------------------------


--------------------------------------------------------------------
THE SIDE MENU
--------------------------------------------------------------------
<div id="sidemenu">
<noscript>
<ul>
<li class="LeftHandMenus_l0_off"><a href="">Home</a><li>
<li class="LeftHandMenus_l1_off"><a href="">Level 2</a><li>
</ul>
</noscript>
</div>
--------------------------------------------------------------------
- this is the contents of the side menu that is displayed when javascript is disabled, also serves as a way for spiders to find pages in the site.
- for each level, use the classes  LeftHandMenus_l{level}_on and LeftHandMenus_l{level}_off.  The topmost level is 0.
- the two anchors listed are just examples

--------------------------------------------------------------------


--------------------------------------------------------------------
THE LANGUAGE TOGGLE
--------------------------------------------------------------------
<div id='language'></div>
--------------------------------------------------------------------
- this is included in the gov_showHeader() function
- the contents are automatically replaced with the language text 
  and link to the corresponding page in that language (if available)
--------------------------------------------------------------------


--------------------------------------------------------------------
THE HEADER LINKS
--------------------------------------------------------------------
<div id='headerlinks'></div>
--------------------------------------------------------------------
- this is included in the gov_showHeader() function
- automatically replaced with the contents of arrHeaderLink[] array
--------------------------------------------------------------------
