Late creation of slides, e.g., after receiving the response of a HTTP request

This issue continues the discussion started at JoshDSommer/nativescript-slides#37 (comment)

@TheOriginalJosh I pulled the current version of nativescript-ng2-slides and played around with it. I have probably found a way to solve the use case 'late creation of slides'.

What I did:

• I created a method manualInit() in SlidesComponent and moved the code from ngAfterViewInit to this new method.
• In AppComponent I implemented ngAfterViewChecked and checked if the slides view has children. If yes, then I call manualInit().

However, this implementation is not very nice. I can imagine that SlidesComponent implements ngAfterViewChecked and checks every time it is called if the number of children has changed (= very basic way of detecting new slides). If the number has changed then SlidesComponent initialises its internal data structures.

Since I am not an expert regarding nativescript and angular, and you know your code better than me I would appreciate if you could add this behaviour to your library -- that is if it makes sense to you.

I attach the files contained in the folder slides/app of your project (except for the folder App_Resources) so you can have a look and give it a go: app.zip

Please let me know if you are unable to work on it till next Wednesday -- I need to finish my app very soon.

Thank you!

Works for me now.
