* Adds support for having multiple interface state delegates.
Hopefully in a performant way.
* Switch to respondsToSelector for int del instead of separate object
* Add CHANGELOG
* Make ASDisplayNode+InterfaceState.h public
* Huy's comments
* Don't even bother removing since it's a weak hash table.
* fix SIMULATE_WEB_RESPONSE not imported #449
* Fix to make rangeMode update in right time
* Fix pager node for interface coalescing
* Fix typo
* change log
* - [ASDisplayNode] Consolidate main thread initialization and allow apps to invoke it manually instead of +load.
Additionally this has a few minor fixes for Yoga support, and adds some basic
but universally valuable callbacks like -nodeDidLoad to ASNodeController.
* Small fix for handling _layoutVersion.
* Remove poking the scale accessor
With these changes, I'd also like to propose that we move ASNodeController
out of Beta (renaming the files without +Beta). Let me know what you think!
Because we don't support ASNodeController directly in ASCV / ASTV, it is still
important to allow flipping the ownership in certain cases (in particular, for
root CellNodeController objects that should follow the lifecycle of the
ASCellNode rather than owning the ASCellNode).
