As title.

I work with scientific data, and it's essential I know what method is used if I am going to publish or present outputs from Orange. Whatever method is used, it would be nice if the distance map had the same linkage options as found in the Hierarchical Clustering widget!

Relevant methodology should be mentioned in the docs.
