Currently, the main clustering function is claraclust. Rename it to cluster_clara and create the new main function perform_clustering which then either calls cluster_clara or the new function cluster_clarans. Regarding the fuzziness, it's probably best to not use it in the function names, but rather as an argument, to make clear that the functions can also be used for non-fuzzy analyses.
