INADA Naoki cb41b2766d bpo-29463: Add docstring field to some AST nodes. (#46)
* bpo-29463: Add docstring field to some AST nodes.

ClassDef, ModuleDef, FunctionDef, and AsyncFunctionDef has docstring
field for now.  It was first statement of there body.

* fix document.  thanks travis!

* doc fixes
