The ClusterEvaluator has methods for both inter-cluster density and
intra-cluster density. The former computes the density using the cluster
centers, while the latter uses a set of representative points extracted
from the clustered points. This reduces the computational overhead of
calculating a density from all of the points from each cluster.
The unit test uses synthetic data and produces reasonable looking
results afaict. Have you had negative experiences with that?

It was my understanding that the ClusterEvaluator included an attempt
to provide this measure with intra-cluster density per cluster though
it looks like that output has been removed?
