simplified roff calculation
Merge remote-tracking branch 'origin/master' into simplertransfs
use selected object rather then reinitialising suzanne mesh, dont run script on import, unless started from console
now runnable with any obj, outsourced suzanne into one method
Added Paper for Mean Shift Clustering
wrote new meanshift module
Merge branch 'alex' of https://github.com/katosh/sym into alex
added plot_clusters, improved clustering
changed meanshift parameters for suzanne
fixed bug (division by 0), also fixed meanshift to fit algorithm from wikipedia
adjusted cluster parameters for suzanne, fixed convergence detection
worked on Transformations class, whitespace fixes
more consistent data abstraction / object orientation
removed unused quantities from Transf, added metric and group operations
added rnor/roff computation from co, added random signature selection, bugfixes
refactored code, outsourced everything groupspecific to Reflection, removed deprecated/unused code
reverted to old (wrong) metric, splitted mean shift and clustering
'fixed' clustering by using fake metric and fixing the d(x,m) bug, had to introduce identity
