A simple way to get a dynamic tree view in your Ember.js apps without losing too much control when the procedural API of jsTree is translated into the more declarative style of Ember properties.
Just call grunt in the directory.
Check tests/index.html for usage. The basic idea is that the js-tree component has a list
of roots which you can manipulate. It's important to use Ember.Array's array operations,
for example objectAt and pushObject. Each item in the roots should be
EmberJsTree.Node objects.
