Refactored PrimitiveAnalyser and dependencies:
* work done to integrate already grown regions with the PrimitiveAnalyser
(still to brush up -> late development stage still)
Added scaling factor debug display
Added functionality for new curvature coloring vis
* implemented swing combo box for the draw settings panel which includes 3
3 display modes for the curvature of an object
* added functionality to the MeshReasoningView visualization class
* backend functionality at the level of the CurvatureCalculation and
Curvature utility classes also implemented
* curvature coloring able to be displayed with this: mean curvature,
Gaussian curvature and estimated curvature coloring
Refactor Apperance handling for added triangles:
* implemented apperance copying for added triangles
Handling of number of clustes for KMeans:
* changed the threshold for handling num. of clusters using the num. of
vertices of the model (2.5 % of num of vertices is new threshold) and min
5 clusters are necessary
* small brush-up of region processing parts
