Introduce the use of boost::shared_ptr for class members * mesh.h: private memeber is now boost::shared_ptr<const dolfin::Mesh> instead of dolfin::Mesh The class now derives only from octave_base_value and no more from dolfin::Mesh * mesh.cc: the constructor now takes care of the boost::shared_ptr < > * fem_get_mesh.cc, fem_init_mesh: now use boost::shared_ptr < >
