- In order to proceed in a step-by-step fashion, I moved many functionalities, mainly related to the caching sub-system thats needs more efforst in testing and well-designing, to the old_new_features directory.
I plan to recycle that code in futures features addings.
- I removed the SparseInstance interface and I replaced it , with some differencies, with the TreeSetInstance class.
- I removed the ClusteringAlgorithm interface in order to change some design details in a more simple way.
- I finished the JaccardDistanceTest suites.
- I started the rethinking of the Kmedoids class.

Bye!
