*	@brief Accordion Component
*
* @detailed This is the main javascript file used code that is common to both Admin and Public Division
* The object.init function takes 5 parameters: 
*   - id of the accordion 
*   - the header element tag
*   - whether the panels should be expandable independently (optional)
*   - the index of the initially expanded section (optional)
*   - the class for the active header (optional)
*
*  Expand a particular section by its index, for example parentAccordion.pr(0,1), with the second parameter being the index of the section. If you don't want any section to be expanded by default then use -1 for the initially expanded index in the initialization function, example accordion.init('accordion','h3',0,-1,'selected')
