/**
 * CHANGES v.2.1.3 - Made it $.noConflict() compatible v.2.1.2 - Fixed bug in
 * which nested fieldsets do not work correctly. v.2.1.1 - Forgot to put the new
 * filter from v.2.1 into the if (settings.closed) v.2.1 - Changed
 * jQuery(this).parent().children().filter( ELEMENTS HERE) to
 * jQuery(this).parent().children().not('label'). Prevents you from having to
 * guess what elements will be in the fieldset. v.2.0 - Added settings to allow
 * a fieldset to be initiated as closed.
 * 
 * This script may be used by anyone, but please link back to me.
