Color mapping in Scatterplot and initial measures.

- Scatterplot: can now map any floating point data to colors;
- Scatterplot: somewhat optimized geometry/material updates;
- Removed anything related to labels where it was not necessary;
- Added observers to implement distortion (via measures) visualization;
- Added skeleton implementations of NP and silhouette.
