Utility for creating the Pecan application object. This function should
generally be called from the ``setup_app`` function in your project's
``app.py`` file.
:param root: A string representing a root controller object (e.g.,
"myapp.controller.root.RootController")
:param static_root: The relative path to a directory containing static
files. Serving static files is only enabled when
debug mode is set.
:param logging: A dictionary used to configure logging. This uses
``logging.config.dictConfig``.
:param debug: A flag to enable debug mode. This enables the debug
middleware and serving static files.
:param wrap_app: A function or middleware class to wrap the Pecan app.
This must either be a wsgi middleware class or a
function that returns a wsgi application. This wrapper
is applied first before wrapping the application in
other middlewares such as Pecan's debug middleware.
This should be used if you want to use middleware to
perform authentication or intercept all requests before
they are routed to the root controller.
All other keyword arguments are passed in to the Pecan app constructor.
:returns: a ``Pecan`` object.
