Typo in classes example

[hamid914]

The description for getName member function is placed out of the def invocation:

cpp-pybind11-playground/classes/src/main.cpp

Line 34 in c2a3d9a

.def("getName", &Dog::getName), "Getting the dog's name";

However the compiler ignores that description and the example works:
