Visualize distance matrices by MDS

Description (last modified by abeham)

I want to be able to visualize a distance matrix given as a double matrix by multidimensional scaling (MDS).

Also a feature vector should be defined which allows to color the entities differently.

Don't recalculate MDS when names are set.

The view is not necessary, MDS algorithm already integrated into trunk. A generic scatter-plot view for double matrices should be implemented.

The branch was deleted in #2438. Additionally, with t-SNE we may have a better algorithm for visualizing high-dimensional data in 3.3.15.
