Functor1D class for one-dimensional functions.

It is used to wrap in a very simple and convenient way:

  • any C++ callable object implemention double operator()( double )
  • a free C function of type double ()(double )
  • a member function with the correct signature like Foo::Eval(double ). In this case one pass the object pointer and a pointer to the member function (&Foo::Eval)
