Invending mode permits to see on the fly the result of your
changes by automatically reloading the web page whenever
your python code or the page template changes.
It is meant as a way to improve developer experience when
experimenting with changes to the source code, just put
your browser and your test editor one near the other and
enable inventing mode to start experimenting.
To permanently enable inventing mode when in debug add
debugbar.inventing=True option to your application configuration.
