       Given a field(2) fh defined in a domain Lambda, this function computes the level set defined by {x in
       Lambda, fh(x) = 0}. This level set is represented by the geo(2) class.

       level_set - zero level set of a field (rheolef-7.2)

       The option class leve_set_option controls the slit of quadrilaterals into triangles for tridimensional
       intersected surface and also the zero machine precision, epsilon.

       struct level_set_option {
         bool split_to_triangle;
         Float epsilon;
         level_set_option()
          : split_to_triangle(true),
            epsilon(100*std::numeric_limits<Float>::epsilon())
            {}
       };
