Add analytics tracking code

[techieshark]

Analytics should track at least:

• [ ] screen views
• [ ] do visitors scroll to bottom of stories
• [ ] individual story passes & saves/likes
• [ ] device used
• [ ] geo metrics
• [ ] session length
• [ ] time spent on discover mode v map mode
• [ ] session interval
• [ ] most visited page
• [ ] top search(es)

Other things to think about:

• [ ] interactions with more info & directions buttons
• [ ] interactions with photos (taps on photo)

Any specific analytics setup will have to wait until we hear more about what is going to be tested, and currently it sounds like the testing will just be qualitative.

Hello there

I've added a tracking tag for mixpanel but get no love firing it in/with localhost (or whatever you kids call it these days. In my day a milkshake, ferry to manly, a ticket to the pictures and a bag of lollies were 20c!)

<!-- start Mixpanel --><script type="text/javascript">(function(e,a){if(!a.__SV){var b=window;try{var c,l,i,j=b.location,g=j.hash;c=function(a,b){return(l=a.match(RegExp(b+"=([^&]*)")))?l[1]:null};g&&c(g,"state")&&(i=JSON.parse(decodeURIComponent(c(g,"state"))),"mpeditor"===i.action&&(b.sessionStorage.setItem("_mpcehash",g),history.replaceState(i.desiredHash||"",e.title,j.pathname+j.search)))}catch(m){}var k,h;window.mixpanel=a;a._i=[];a.init=function(b,c,f){function e(b,a){var c=a.split(".");2==c.length&&(b=b[c[0]],a=c[1]);b[a]=function(){b.push([a].concat(Array.prototype.slice.call(arguments, 0)))}}var d=a;"undefined"!==typeof f?d=a[f]=[]:f="mixpanel";d.people=d.people||[];d.toString=function(b){var a="mixpanel";"mixpanel"!==f&&(a+="."+f);b||(a+=" (stub)");return a};d.people.toString=function(){return d.toString(1)+".people (stub)"};k="disable time_event track track_pageview track_links track_forms register register_once alias unregister identify name_tag set_config reset people.set people.set_once people.increment people.append people.union people.track_charge people.clear_charges people.delete_user".split(" "); for(h=0;h<k.length;h++)e(d,k[h]);a._i.push([b,c,f])};a.__SV=1.2;b=e.createElement("script");b.type="text/javascript";b.async=!0;b.src="undefined"!==typeof MIXPANEL_CUSTOM_LIB_URL?MIXPANEL_CUSTOM_LIB_URL:"file:"===e.location.protocol&&"//cdn.mxpnl.com/libs/mixpanel-2-latest.min.js".match(/^\/\//)?"https://cdn.mxpnl.com/libs/mixpanel-2-latest.min.js":"//cdn.mxpnl.com/libs/mixpanel-2-latest.min.js";c=e.getElementsByTagName("script")[0];c.parentNode.insertBefore(b,c)}})(document,window.mixpanel||[]); mixpanel.init("ebfad93b8446288ed0344dce7bfcd426"); </script><!-- end Mixpanel -->
