Function FreeClusterer

deps/tesseract/classify/cluster.cpp:547–563

* This routine frees all of the memory allocated to the * specified data structure. It will not, however, free * the memory used by the prototype list. The pointers to * the clusters for each prototype in the list will be set * to NULL to indicate that the cluster data structures no * longer exist. Any sample lists that have been obtained * via calls to GetSamples are no longer valid. *

 * @note History: 6/6/89, DSJ, Created.
