/**
* Interface for managing analytics. This is highly platform dependent, and mostly matches
* Google Analytics. The reason the interface is here is to remove the dependency to an
* implementation from most other places.
*
* The methods exported from this interface more or less match those needed by us in the
* universal analytics package, see https://unpkg.com/@types/universal-analytics@0.4.2/index.d.ts
* for typings. We mostly named arguments to make it easier to follow, but didn't change or
* add any semantics to those methods. They're mapping GA and u-a one for one.
*
* The Angular CLI (or any other kind of backend) should forward it to some compatible backend.
