  * @description
  * <b>Added in Umbraco 8.7</b>. Service for dealing with Block Editors.
- * 
+ *
  * Block Editor Service provides the basic features for a block editor.
  * The main feature is the ability to create a Model Object which takes care of your data for your Block Editor.
- * 
- * 
+ *
+ *
  * ##Samples
  *
  * ####Instantiate a Model Object for your property editor:
- * 
+ *
  * <pre>
  *     modelObject = blockEditorService.createModelObject(vm.model.value, vm.model.editor, vm.model.config.blocks, $scope);
  *     modelObject.load().then(onLoaded);
  * </pre>
  *
- * 
+ *
  * See {@link umbraco.services.blockEditorModelObject BlockEditorModelObject} for more samples.
- * 
+ *
