* Use ast module to find class definition * Add NEWS entry * Fix class with multiple children and move decorator code to the method * Fix PR comments 1. Use node.decorator_list to select decorators 2. Remove unwanted variables in ClassVisitor 3. Simplify stack management as per review * Add test for nested functions and async calls * Fix pydoc test since comments are returned now correctly * Set event loop policy as None to fix environment related change * Refactor visit_AsyncFunctionDef and tests * Refactor to use local variables and fix tests * Add patch attribution * Use self.addCleanup for asyncio * Rename ClassVisitor to ClassFinder and fix asyncio cleanup * Return first class inside conditional in case of multiple definitions. Remove decorator for class source. * Add docstring to make the test correct * Modify NEWS entry regarding decorators * Return decorators too for bpo-15856 * Move ast and the class source code to top. Use proper Exception.
