Library to make werkzeug working with asyncio.

• Use Python 3.5 async syntax.
• New ~keep_context_factory. It works like ~context_coroutine, but simple code.
• Async version of Local, LocalStack and LocalManager. They implement __release_local__ method.

• Async versions of Local, LocalStack and LocalManager.

• Locals work on asyncio Tasks. werkzeug.local.Local or werkzeug.local.LocalStack must be patched with aiowerkzeug.local.patch_local

  Patched werkzeug.local.Local or werkzeug.local.LocalStack use current asyncio.tasks.Task to determine context.

• Decorator factory to mark coroutines to run in a context. Useful for Flask. It allows to run corountines in new asyncio.tasks.Task inside a specific context.

  For example, in Flask to run coroutines in Application context it is possible to create a decorator like that:

  def _get_app_context():
      return current_app.app_context()
  
  app_coroutine = partial(context_coroutine, ctx=_get_app_context)
  
  @app_coroutine
  def foo_bar():
      print(current_app.debug)
  
  @flask_app.route('/')
  def caller():
      asyncio.ensure_future(foo_bar())

• Asyncio HTTP server runner with reload

  $ python aiowerkzeug/serving.py --reload app_test.app

• Form parser
• Debug middleware
• Static files middleware
