onSlideChanged & onStoryChanged Functions

[jtkeyva]

Is your feature request related to a problem? Please describe.
Would be great to be able to call a custom function when a slide starts & when a slide ends. For instance once a video is finished it can trigger an onSlideEnd / videoViewed function to add a view count to the database. Also, would be useful to have a function fire onSlideStart

Describe the solution you'd like
Ability to define a custom function once a slide begins and ends.

Describe alternatives you've considered
Hack the code or use a pageview base approach which has onPageChanged

Additional context
Also makes sense to have onStoryChanged so that when a new story starts you can run a different function.

Hi JT, you can add event listener using controller to achieve desired behaviour. Also you can manipulate flow by setting interceptor. Please take a look at example project.

Thank you! I will have a look at the code and the docs. Perhaps we can add to the readme something like:

Run custom events/functions on slide change and story change

Documentation contains useful information about the controller but it looks like I need to update the documentation as well.
