* @class GObservationRegistry
*
* @brief Interface definition for the observation registry class
*
* The registry class allows the registration of observations that are not
* necessarily compiled into the GammaLib. It uses the static members
* m_number, m_names, and m_obs which are allocated globally to keep track
* of observations that are available throughout all linked libraries. To
* register an observation it is sufficient to add
*
* const GXXXObservation g_obs_XXX_seed;
* const GObservationRegistry g_obs_XXX_registry(&g_obs_XXX_seed);
*
* at the top of the .cpp file of the observation. Here, XXX is a unique
* name that describes the instrument for which the observation class is
* implemented.
