* @class TAO_Codeset_Translator_Factory
*
* @brief Abstract base class for factories providing codeset translators
*
* The codeset translator factory is a loadable service object. It is used to
* supply the actual translator used in converting between two codesets. The
* intent of using a factory is to avoid requiring codeset translators to be
* multiply inherited both from the translator base class and the service
* object base. The translator factory is also responsible for assigning
* translators to CDR streams. Since there is no common base class between
* input and output CDRs, the assingment code must be duplicated.
