Summary 0000474: IMPLEMENTED: k-means clustering was merged with new clustering unit
Description k-means++ algorithm now provide new-fashion clusterizaton interface, similar to that of new hierarchical clustering unit. Old interface was left for backward compatibility.

The most important change is that new version of algorithm stores centers in ROWS of the resulting matrix instead of columns. However, old code still continue to work because old version of the algorithm was left unchanged.
