 AutoLayout.js implements Apple's [Auto Layout](https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/Introduction/Introduction.html) and [Visual Format Language](https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/VisualFormatLanguage/VisualFormatLanguage.html) in Javascript. Auto layout is a system which lets you perform lay out using mathematical relationships (constraints). It uses the awesome [Cassowary.js](https://github.com/slightlyoff/cassowary.js) library to do the actual constraint resolving and implements Apple's constraint system and Visual Format Language (vfl) on top of that.
