CONTRIBUTING
  ============
  
  * Open a [Pull Request (PR)](https://github.com/angular-ui/ui-select2/pull/new/master)
  * Make sure your PR is on a **new branch** you created off of the latest version of master
  * Do **not** open a PR from your master branch
  * Open a PR to start a discussion even if the code isn't finished (easier to collect feedback this way)
  * Make sure all previous tests pass and add new tests for added behaviors
