The template parameter StreamLinesTraits_2 has to be
instantiated by a model of the concept StreamLinesTraits_2.
This class provides a vector field specified by a set of sample points defined on a triangulated domain. All sample points are inserted to a Delaunay triangulation, and for each point p in the domain located in a face f, its vector value is interpolated from the vertices of the face f.
