Use flat clustering algorithms from sklearn to cluster the patterns

[benvanwerkhoven]

There are many clustering algorithms in sklearn, we need to investigate which of these we can use for our application. Then we can also make a comparison of the quality of the flat clusterings produced by the different clustering algorithms. This is a lot of work because each clustering algorithms has different parameters that need to be tuned to our problem case to get good results.

This can be fun, if noone minds ! :) Unless you need a Java programmer on other issues, of course.

I can also take the other two related issues: #9 and #10.
