Consolidated TestVisualizer and reduced its complexity by a great
amount. Only one function for producing images remains, combining all
functionality of previous functions. Much easier to use now!
Added interfaces for classification providers. Will extend soon to all
relevant clustering algorithms.
Merge branch 'master' of github.com:Roland-Winkler/EDMOAL
