This class plays a role of wrapper of Umfpack library.

And only necessary functions are provided here. However, we we can easily extend this class with new methods wrapping functions of Umfpack library. Because Umfpack only works with int/double, (e.x umfpack_di_symbolic, etc) or long/double, (e.x umfpack_dl_symbolic) Class template specialization approach seems to be the best!
