    Pollinate Analytics Tracking

    Credit to Robert Stevenson-Leggett @ Building Blocks UK for creating the 
    Google Analytics Event Tracking jQuery Plugin on which this is based.

    This plugin will do the following:
    - Track events if data attribute specified by the trackAttribute is present
    - Track downloads as pageviews
    - Track exits to external sites
    
    Usage:
    
    $(function () {
    //track all links with trackAttribute, downloads, and exits
    $("a").gaTrack({
    trackAttribute: 'data-ga-track',
    categoryAttribute: 'data-ga-category',
    actionAttribute: 'data-ga-action',
    trackDownloads: true,
    trackExits: true
    });
    });
    */

    //Wrap the track event function
    var trackEvent = function (category, action, label, value) {
        _gaq.push(['_trackEvent', category, action, label, value]);
    };

    //Wrap the track pageview function
    var trackPageView = function (href) {
        _gaq.push(['_trackPageview', href]);
    };

    //Check if link is external
    var isExternal = function (url) {
        var match = url.match(/^([^:\/?#]+:)?(?:\/\/([^\/?#]*))?([^?#]+)?(\?[^#]*)?(#.*)?/);
        if (typeof match[1] === "string" && match[1].length > 0 && match[1].toLowerCase() !== location.protocol) {
            return true;
        }
        if (typeof match[2] === "string" && match[2].length > 0 && match[2].replace(new RegExp(":(" + {
            "http:": 80,
            "https:": 443
        }[location.protocol] + ")?$"), "") !== location.host) {
            return true;
        }
        return false;
    };

    var defaultOptions = {

        trackDownloads: true,
        //Track exits to links not within same domain.  Note, selector must be broad enough to include these link (i.e. $('a').gaTrack({ trackExists: true });

        useLabel: false,
        //Whether to look for a value

        //false = track as soon as the plugin loads, true = bind to an event

    //
    //
