// SHORTCODES
// This shortcode will allow you to add a link to a wysiwyg box and have event tracking added to the link
// Use like this, for example: 
// [analyticsLink url='http://www.crosbymarketing.com' target='_blank' evcat='external_links' evaction='click' evlabel='home_learn_more' textlink='Learn More']
// target="_blank" is the default behavior for the link.
// ga_link is the default event category; click is the default event action; learn_more is the default event label; Read More is the default textlink
// It will output the hyperlink and use the textlink as the clickable text for the link.  The event are the values you want to set for Google Analytics
