Implement Caliper.io

[honglio]

Caliper seems like a great fit for us so let's try it out.

I've been given a private signup.

We need this at the top of the

, only needed on /condo-search:

<script type="text/javascript"> var Caliper = { config: { apiKey: "252c0ee8-41f6-4575-84b8-1bf572be4ffc" } }; </script>

Now, download this file: https://d2yr92gots5pio.cloudfront.net/caliper.ember-0.0.3.min.js
It must be included after ember.
They have a help article for AMD/RequireJS but I don't think that applies to our component.json approach?

One thing I'm not sure of is whether we should make this an optional include, such as for running only in production later. If it's optional (i.e. controlled by environment variable), I'm not sure if we have the capability to build/not-build it via component? Anyway, for now we'll want to test it everywhere so no harm baking it in permanently for the short term.

After Codeship is really worked.

Afraid of this tracking tool will slow down my app by waiting some js download/upload from overseas.
