/**

* jQuery makeCollapsible
 
−
*
 
−
* This will enable collapsible-functionality on all passed elements.
 
−
* Will prevent binding twice to the same element.
 
−
* Initial state is expanded by default, this can be overriden by adding class
 
−
* "mw-collapsed" to the "mw-collapsible" element.
 
−
* Elements made collapsible have class "mw-made-collapsible".
 
−
* Except for tables and lists, the inner content is wrapped in "mw-collapsible-content".
