Spelling mistake in readme

https://github.com/cloudfoundry-community/cf-python-client/blob/master/README.rst
On the above mentioned page, currently :

app = client.v3.apps.get("app-guid")
print("App name: %s" % app["name])
space = app.space()
print("Space name: %s" % space["name])
org = space.organization()
print("Org name: %s" % org["name])

There's missing the exit quotations after "name".

Kind regards.
