Is there a way to remove the option to export to pdf from the ui-grid dropdown menu? I want to keep the ability to export to csv, but cannot figure out how to remove the pdf feature without removing all export capability.

I edited [this plunker](http://plnkr.co/edit/mLMY1IXhNlN25yObDAN6?p=preview) from the docs to remove all of the scripts and JavaScript that are relevant to the pdf exporter. This effectively disables the functionality, but the option to export to a pdf is still available from the menu.

```
app.controller('MainCtrl', ['$scope', '$http', function ($scope, $http) {
  $scope.gridOptions = {
    columnDefs: [
      { field: 'name' },
      { field: 'gender', visible: false},
      { field: 'company' }
    ],
    enableGridMenu: true,
    enableSelectAll: true,
    exporterCsvFilename: 'myFile.csv',
    exporterCsvLinkElement: angular.element(document.querySelectorAll(".custom-csv-link-location")),
    onRegisterApi: function(gridApi){
      $scope.gridApi = gridApi;
    }
  };

```
