  $(document).delegate("a", "click", (evt) ->
    # Get the anchor href and protcol
    href = $(this).attr("href")

    # Stop the event bubbling to ensure the link will not cause a page refresh.

      # Note by using Backbone.history.navigate, router events will not be
      # triggered.  If this is a problem, change this to navigate on your
      # router.
