   2     MoinMoin - Collapsible Section  macro
   3 
   4     This macro provides a way to display the contents of another page into
   5     an HTML div that can be collapsed and expanded. Its useful for including
   6     supplemental information in a page that normal users might not care about.
   7 
   8     Example Usage:
   9      collapsed by default:
  10         <<CollapsibleSection("Title for Section", "PageName")>>
  11      expanded by default
  12         <<CollapsibleSection("Title for Section", "PageName", 1)>>
