Release highlights

• New datastructure VertexColorMesh3D, which represents a triangle mesh with vertex colors
• Added reader/writer for ply mesh format
• New approximation method for computing a low-rank Gaussian process, based on the Pivoted Cholesky decomposition.
• Renamed Vector to EuclideanVector, in order to avoid name clashes with Scala's vector class

Breaking changes

The class Vector was renamed to EuclideanVector. The same applies to the concrete instances such as Vector1D, Vector2D and Vector3D. A simple search/replace will make everything work again.

Bugfixes and minor changes

• New object StatisticalModelIO with more intuitive names for reading/writing IO (fixes #249)
• Correct computation of closest point for degenerated triangles (fixes #262)
• Computation of mesh metric based on closest point to surface rather than closest vertex (fixes #252)
• Made Domain of DiscreteScalarField contravariant (fixes #241)
