\subsection{Detailed Description}
A very simple partitioner which partitions the data randomly into the number of desired clusters. 

It has no parameters, and so an instance of the class is not even necessary.

Partition the given dataset into the given number of clusters. 

Assignments are random, and the number of points in each cluster should be equal (or approximately equal).
