[pygccxml-development] FT - recent changes

[Roman Y. <rom...@gm...>]

Hi. I committed few small changes to FT feature.

The main one is the interface change:

Now in order to add new transformation user have to write:

f.add_transformation( output(1), output(2) )

f.transformations property provides access to all function transformations that
should be applied.

The change was necessary because I want the way to apply few function
transformations on a single function.

For example:

struct error_t{};

void do_smth( ..., error_t& );

I want to expose do_smth in 2 ways:

1. as is: def( "do_smth_no_raise", &do_smth );
2. error status is converted by Py++ to exception:

void do_smth_raise(){
    error_t x;
    do_smth( x );
    if x contains error:
       throw actual error;
}

def( "do_smth", &do_smth_raise );


do_smth.add_transformation() #<- use Py++ default behaviour
do_smth.add_transformation( raise_on_error( 0, ... ) )
