// State example:
//
// $stateProvider     
//   .state('state', {
//     url: 'state/:id',
//     template: stateTemplate,
//     controller: stateController,
//     // Expose parameters in display names using {:param} syntax
//     displayName: 'State ({:id})'
//   });

  // Controller for module
  .controller('BreadcrumbsCtrl', function($scope, $state, $stateParams) {

      // Add the current state and params to the scope
      $scope.current = $state.$current;

    });
  })

      // This is just to simplify this example

          var displayName = scope.state.displayName || scope.state.name;

          // Loop through ownParams and replace any expressions with the matching value
          angular.forEach(scope.state.ownParams, function(param, index){
