* Fix sample projects in extra/

* Remove preferredFrameSize test of ASEditableTextNode

* Remove preferredFrameSize from examples_extra

* Add deprecation warning to -[ASDisplayNode preferredFrameSize]

* Add deprecation warning to -[ASDisplayNode measureWithSizeRange:]

* Commit

* Commit

* Remove ASRelativeSizeRange

* Make ASRelativeSize private

* Rename ASRelativeDimension to ASDimension

* Fix examples for ASDimension renaming

* Remove fancy height and width setter

* Fix ASDimension helper

* Update layout related methods and more clearer documentation around how to use it

* Deprecate old ASLayout class constructors

* Don't unnecessary recalculate layout if constrained or parent size did not change

* Use shared pointer for ASDisplayNodeLayout

* Fix rebase conflicts
