Changes

Select the lower left triangle to convert DistanceMatrices to long form.

This makes the return value of delta_values order-compatible with ssd.squareform, i.e. dm.delta_values().values == ssd.squareform(dm) and all(dm.delta_values().index == pd.MultiIndex.from_tuples(itertools.combinations(corpus.index, 2)))
 (commit: 0ee6678)

Fast pairwise comparison function for dataframes.

The result can be concatenated to the output of DistanceMatrix.delta_values() using pd.concat(..., axis=1).

TODO need tests
 (commit: 6393947)

Use KMediods implementation from scikit-learn-extras.

Make sure DistanceMatrix.delta_values does not use the wrong triangle ...
