Adds a native k-means clustering algorithm. Based on a port of PostGIS' ST_ClusterKMeans function, this new algorithm adds a new cluster ID field to a set of input features identify the feature's cluster based on the k-means clustering approach. If non-point geometries are used as input, the clustering is based off the centroid of the input geometries.
