Requires: 
jQuery and Coremetrics libraries

Methods:
init = binds click events to anchors and mapped areas
custom = binds to custom element click event
send = executes the coremetrics function(s) pulling necessary parameters from html and settings 
	-Determines if element is navigational, executing appropriate functions 
debug = allows you to enable debuging in console to see parameters being passed to coremetrics functions on click

Attributes:
Settings = Array includes defaults:
	pageID: false,
	elementCategory: false,
	debug: false,
	boundElements: a, area,
	navClass: nav
