docstring for CppClass

Hi,

I was wondering if we can set docstring in a cppclass easily.
I am using the 0.10 code. I think the docstring is only set
in the generate method, which means, if I call the root module's
generate method, there will be no docstring set for individual classes.
But for methods and functions, the constructor accept a docstring
parameter, which makes adding docstring a lot easier. Why
the cppclass doesn't accept a docstring in construction to make
things consistent?

I am not sure if I missed something here. If so please let me know.
