/**
* 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.
