This class computes the traveling time T using the (single threaded) Fast Iterative Method for arbitrary triangulated meshes. The quality of the result depends on the quality of the triangulation. For a high accuracy the triangulation should not contain too many non-acute triangles. @param the type of the vertices of the triangulation @param the type of the half-edges of the triangulation @param the type of the faces of the triangulation @author Benedikt Zoennchen
