V2

[jridgewell]

TODO:

• Add EmptyView to CollectionView
• UMD support (Export UMD #3)
• Write docs (More docs pls #2)
• @jmeas Clever #render (Inefficient rendering of views #10)
• Bind UI element on #setElement
• Update DOM attributes on re-render (id, class, attributes)

Back burner:

• Look into Marionette.Behavior
  • Dislike wrapping functions and events.
• CollectionView #filter
  • All kinds of problems and tons of code. Best left to a virtual Collection.

Additions:

• Adds Router
• View
  • Add ui hash
• Adds trigger function
  • To be mixed into subclasses, at the Dev's discretion.

Changes:

• Region
  • Trigger detach and detached events when attaching a new view
  • Optimize when a Region's view is removed.
  • Extract placeholder into a Backbone.View class
  • remove #detach and #reattach
• View
  • Optimize rendering a string template.
  • Do not render a Region's placeholder view when using <%= view('name' %> template syntax
  • Regions are no longer attached at the root.
• CollectionView
  • Separate out logic for appending and appending-to Document Fragments
    • This was unnecessarily complex. At times, you would be appending a single modelView. Other times, you would be appending a Backbone.View who's #el was a frag.

Misc Changes

• Convert Grunt -> Gulp
• Cleanup JSHint
