Typo in classes example

[hamid914]

The description for getName member function is placed out of the def invocation: https://github.com/aoloe/cpp-pybind11-playground/blob/c2a3d9a7a83b5cc39eba74c8dcc613f05ac086d7/classes/src/main.cpp#L34 However the compiler ignores that description and the example works:
