Feature: Optional (packaged) mixins

[peol]

This is an idea we've been bouncing around internally for a while. The idea is that we deliver a npm package containing generally useful mixins that may be needed in many use cases. Below I'll outline some of the ones I've identified and suggest this package would contain.

Ideas/feedback welcome!

• getObject cache (Packaged mixin: getObject cache #270)
• Pending call cache (Packaged mixin: Pending call cache #271)
• Normalize Doc QIX API (Packaged mixin: Normalize Doc QIX API #272)
• Garbage collector/memory optimizer (Packaged mixin: Garbage collector/memory optimizer #273)
• Access global/doc from generated APIs (Packaged mixin: Access global/doc from generated APIs #274)
• Generic object state (Packaged mixin: Generic object state #275)

@peol I really like the idea of mixins, but please separate this in two different packages:

1. helpers (Naming, Doc/Global in API,...)
2. caching, garbage collection
   I really like the concept of the pure enigmaJS and we always do the caching in our code, because than we have 100% control

@peol for the topic naming:
I really prefer if qlik would change the api of the engine and this mixings could be the backward compatible option, to don't break existing extensions,...

thanks @konne — the idea here is that these mixins are provided in an opt-in manner. It's not all or none so it's up to you what you want to use :)
