For https://github.com/angular/batarang/issues/84

[nhuttrung]

There are two options for developers show their scope description in Batarang scope tree:

1. Using attribute.
   I propose to use 'ng-batarang' attribute. It works like the ng-app, ng-controller, etc currently supported in Batarang.
   Please note that there is NO additional directive required for ng-batarang. The ng-batarang attribute is just be there for Batarang to look up the scope description.
2. Setting scope description by code.
   And I propose to use $description property.

Thanks! Glad to have PR interest.

Two comments:

• Can you open this as a PR to https://github.com/angular/angular-hint instead of editing dist/hint.js? That's a generated file and will be overwritten. We can cover the code there.
• When you do, please update the commit message to conform to https://github.com/angular/angular.js/blob/master/CONTRIBUTING.md#submitting-a-pull-request
