change log:
1. add BOTH direction support for triangle_count/cluster_coeffcientith.
2. fix extra triangle count with multi edges between tow adjacent vertices.
3. set default value of direction to BOTH for degree_centrality and cluster_coeffcient .
4. add workers for triangle_count and cluster_coeffcient.
5. fix closeness: multi shortest paths cause results illogical.
6. rename rings_detect to rings, rename limit to each_limit which means limit number of rings of each source vertex, and don't do dedup if passed each_limit > 0.
7. unify top for 4 centrality algos: sorted results when top = -1, unsorted results when top = 0.
8. fusiform: rename top to top_similars (expected >= 0).
9. fusiform/rings: add limit param which means max number of results, and remove capacity param and hardcode to 100000000.
