Facebook's css-layout for Titanium

Exploring how it could be used to have a more iOS-autolayout-like layout system on Titanium.

Related JIRA ticket: TIMOB-18479

How I made it work for Titanim via JS

1. Put Layout.js in Resources/Layout.js
2. Add Resources/computeLayout.js to fix css-layout #24.
3. Add Resources/Template.js to translate between ListView-like templates, css-layout and then to actual Titanium views.
4. Play with it in Resources/app.js

How it might be useful for Titanium

Idealy this would replace the existing layout system. Whenever a view is added/changed/removed it would then use the C/Java version of css-layout to compute the top/left/width/height instead of Ti's own system. If Facebook makes css-layout stable it would give us a flexbox layout system much like iOS's autolayout, more flexible then our current one.

Other ideas:

• The Alloy view compiler could run the TSS/inline properties of a full view hierarchy through computeLayout before using them in the create*() statements. The advantage would be that the changes are JS-only, but that would come at a price.
• React (Native)'s way to batch the creation of UI is very similar to how we now use templates for ListView and to what Carbon did as well. Would be nice to have something like Ti.UI.create(<hierarchy>).
