code: public static <T> T flattenOption(scala.Option<T> option) {
          if (option.isEmpty()) {
              return null;
          } else {
              return option.get();
          }
      }
docs: Flattens an option into its value or else null, which is not great but is usually more convenient in Java.
  @param option Optional value -- either Some(T) or None
  @param <T> Any type
  @return The value inside the option, or else null
