Directors and typemap(in) const TYPE&

Hi Mark:

Yesterday I started to use the directors, and it seems the old
'const TYPE&' is not covered, ie, there is only

 %typemap(directorin,parse="d") double "";

and this one is missing

 %typemap(directorin,parse="d") const double& "";


the same for all the basic types 'int, float, short, ....',
although the case for python/std_complex.i is right.

I know that most people will not declare a function like

    double eval(const double& x);

but rather

    double eval(double x);

however, with general template forms

     template <class T>
     T eval (const T& x);

you easily end with situation when you are using const references
even for short types.

I added the missing const TYPES& declaration in python, but given
that the same changes need to be done for the other modules,
I'll rather let you to chose an uniform style for all of them.
