create template for collapsing large amounts of content (see wikipedia:Template:Hidden begin)
<!--
--><includeonly><!--
-->{{#ifeq:{{{showhide|}}}{{{toggle|}}}|left
| <!------------------------------------------------------------------------
showhide = left, so place [show/hide] link on lefthand side:
-------------------------------------------------------------------------
--><div class="NavFrame {{#if:{{{expanded|}}} | |collapsed}} {{{class|}}}" style="position:relative;width:100%;border:{{{border|none}}};{{{style|}}}"><!--
--><div class="NavHead" style="position:absolute;width:3.2em<!--(to accommodate "[show]")-->;background:transparent;"></div><!--
--><div style="font-size:100%;height:1.6em;background:transparent;padding-left:2.8em<!--(should place text just after [show/hide])-->;
text-align:left;font-weight:bold;{{{titlestyle|{{{headercss|}}}}}}">&nbsp;&nbsp;<!--deprecated:-->{{{header|}}}<!---->{{{title|}}}</div><!--
--><div class="NavContent" style="padding-left:0.3em;text-align:left;{{{bodystyle|{{{contentstyle|{{{contentcss|}}}}}}}}}"><!--
