public static ToStringHelper toStringHelper(Class<?> clazz) {
    return new ToStringHelper(clazz.getSimpleName());
  }
Creates an instance of {@link ToStringHelper} in the same manner as {@link
#toStringHelper(Object)}, but using the simple name of {@code clazz} instead of using an
instance's {@link Object#getClass()}.

<p>Note that in GWT, class names are often obfuscated.

@param clazz the {@link Class} of the instance
