Creating containers of non-copyable data types

[haudren]

In relation with #5 , I tried to bind a container of non-copyable data types (They inherit from boost::noncopyable) but pybindgen explictly tries to copy the inner data types. Given how the the code is generated right now, I don't think that there is an easy way to solve this within Pybindgen (I ended up creating a free function that would return a copyable version of the non-copyable objects) but it would be nice to maybe specify it in the documentation ?
