[boost] [extension] factory_map::get() suggestion

Currently, there is no typedef to provide a convenient way to create
variables of the return type of boost::extensions::factory_map::get().
For example, right now I have to do this:

factory_map fm;
std::map<int, factory<word> > & factory_list = fm.get<word, int>();

It would be ideal to do this instead:

factory_map fm;
factory_map::type& factory_list = fm.get<word, int>();

Could this be done?
