示例1: getUpperBoundCodeForUntypedValue

 /**
  * @brief Find the first code which is greater than the specified typed
  *        value, similar to std::upper_bound().
  * @warning value must not be NULL.
  *
  * @param value A typed value, which can be either the exact same Type as
  *        the values in this dictionary, or another Type which is comparable
  *        according to LessComparison.
  * @param value_type The Type that value belongs to.
  * @return The first code whose corresponding uncompressed value is greater
  *         than value. May return numberOfCodes() if every value in the
  *         dictionary is less than or equal to value.
