  * Pointer Events Polyfill: Adds support for the style attribute "pointer-events: none" to browsers without this feature (namely, IE).
  * (c) 2013, Kent Mewhort, licensed under BSD. See LICENSE.txt for details.
+ *
+ * Modifications for clicks on LABEL tags associated with radios or checkboxes where simulated event triggers do not 
+ * bubble to their corresponding input fields when the events are $.delegate'd on IE9
