WIP Tree UI Core Bundle

The Tree UI bundle is a WIP to replace the CMF TreeBrowserBundle.

Feature parity with TreeBrowserBundle:

• Tree browser: YES
• Tree form type: YES
• Context menu: YES (with FancyTreeView)
• Drag and drop: YES (with FancyTreeView)
• Tree state memory: NO, not yet

Some additional important features:

• Metadata system (including annotations)
• Zero configuration for node hierachy (this is done via. metadata)
• Configurable CRUD routes
• No coupling to models or views
  • Provides API for models to implement, e.g. PHPCR-ODM, ORM, Filesystem
  • Provides API for view controllers, e.g. FancyTree, ElFinder.
• Specific models / views packaged seperately
  • Except for Filesystem (zero-dependencies, good for testing)
  • and .. Static HTML view, pretty useless atm, but at least it doesn't have any deps :) .. again good for testing.
• Multi-select form type
