Is the screenview the intent, or the state?
    State
        These really communicate what's happening in the app. Intents don't really do that
    Intent
        Timings may make a bit more sense this way
    Both?

A rider that allows logging events
Send at the end of each request


How would we log intents?
How would we log states?


Config
=======
* Tracking code
* Debug


To Implement
=============
  Done:
  Responses per round-trip are logged as screens
  Rider gives access to raw GA for transaction logging
  Raw Intents
  Raw States
  Raw Slots
  App version logging
  Device capabilities
  Start/end session control
  locale logging
  Rider for logging custom events

  To Verfiy:
  Exceptions
  per-intent timings (from a state)


  Docs

Not going to implement
========
* Ability to set geographical override. Could still do it manually via other params
* Making only intent logging interactive (since I can't see bounce metrics anywhere anyway)
  if a user has linked their account into something or other
  events from responses doc

Things we've seen before
* Logging custom events (pretty much on each reply)
* Logging exceptions
* Logging transactions (ordering)
* Setting a custom dimension (Formerly also for skill/AL separation)
* Session control for session start/end

Nice to add
=====
* Safety around parameters. Don't just log [object Object], give a warning when that is happening
* Detect device capabilities and put that in the models section
* Detect function name and version, send in the ds attribute? Or send it in the application tracking attribute.
* Ability to set the geographical override in skills that have a ZIP code
* ul, based on the request locale
* Document location URL to set our current state? Or maybe just the title?
* Only pageview events should be interactive. All other events are non-interactive
* timings: What are the categories?
* Know if the user has linked their account. Probably through acuisition channel? Or something else?

Can mobile apps do?
=========
Bounce rate. The user invokes a single intent, but nothing else
Language: Yes

To Know:
Hit type values
 'pageview', 'screenview', 'event', 'transaction', 'item', 'social', 'exception', 'timing'.
