      Function object implementing sign capabilities
  
      Returns the sign of x. i.e. -1, 0 or 1, according
      x is less than @ref Zero, @ref Zero or greater than @ref Zero.
  
      For floating,  the sign of @ref Nan is @ref Nan
  
      @par Semantic:
  
      @code
      T r = sign(x);
      @endcode
  
      is similar to:
  
      @code
      T r = (x > 0) ? T(1) : ((x < 0) ? T(-1) : ((x == 0) ? 0 : Nan<T>()));
      @endcode
