/**
* Push a GA ecommerce.
*
* Ecommerce tracking allows you to measure the number of transactions and
* revenue that your website generates. On a typical ecommerce site, once a user
* clicks the "purchase" button in the browser, the user's purchase information
* is sent to the web server, which carries out the transaction. If successful,
* the server redirects the user to a "Thank You" or receipt page with
* transaction details and a receipt of the purchase.
*
* @see https://developers.google.com/analytics/devguides/collection/analyticsjs/ecommerce
* @see https://developers.google.com/analytics/devguides/collection/gajs/gaTrackingEcommerce
*
* @note Important! The Ecommerce plug-in should not be used alongside the

* - eventValue: int
* (optional) Values must be non-negative. Useful to pass counts (e.g. 4 times).
* - non-interaction: bool
* (optional) A boolean that when set to true, indicates that the event hit
