* Remove background deallocation helper code
Last use removed in Texture with #1840, now PINS no longer uses it either. Less OOMs is so nice.
* remove methods from docs
* Renames AS_EXTERN and ASViewController
To ASDK_EXTERN and ASDKViewController.
This is to avoid conflicting with AuthenticationServices in
Xcode 12
* Fix up examples and docs
* Add bit about updating ASViewController rename
* [Dev docs] Node Lifecycle
Here is my draft on a new documentation aims at people interested in learning about technical details of the lifecycle of ASDisplayNode, as well as its interface and loading states. Hopefully it'd be useful for others who want to ramp up and hopefully start contributing to the framework.
Let me know if there are other topics I should cover, or anything I should explain more/dig deeper, or something that is wrong/no longer valid (imposter syndrome much!). Cheers!
* Update node-lifecycle.md
* Address comments
