``gaussian_mixture_clusterer``
==============================

Gaussian mixture model clusterer for continuous datasets. Learns from a dataset object implementing the ``clustering_dataset_protocol`` protocol and returns a clusterer term that can be used for assigning new instances to clusters and exported as predicate clauses.
