 All included operations work on varying data types and are implemented both for CPU and GPU.
 The package consists of the following operations:
 
-* **Graclus:** Greedy clustering algorithm of picking an unmarked vertex and matching it with one its unmarked neighbors (that maximizes its optionally edge weight).
