  /**
   * (Blueprints Extension) Sets multiple properties in one shot against Vertices and Edges without
   * saving the element. This improves performance avoiding to save the graph element at every
   * property set. Example: <code>
   * vertex.setProperties( "name", "Jill", "age", 33, "city", "Rome", "born", "Victoria, TX" );
   * </code> You can also pass a Map of values as first argument. In this case all the map entries
   * will be set as element properties: <code>
   * Map<String,Object> props = new HashMap<String,Object>();
   * props.put("name", "Jill");
   * props.put("age", 33);
   * props.put("city", "Rome");
   * props.put("born", "Victoria, TX");
   * vertex.setProperties(props);
   * </code>
   *
   * @param fields Odd number of fields to set as repeating pairs of key, value, or if one parameter
   *     is received and it's a Map, the Map entries are used as field key/value pairs.
   * @param <T>
   * @return
