A suggestion for the basic _config_get

Is there any reason not to include 
```
        'result': serialize_settings(node_addon, user)
```
in the default return value? 
We should try to make the template easy to use for the 90% use case. Most add-ons will be for 3rd party services, particularly 3rd party storage and productivity services. Consequently, the cookiecutter won't serve "internal" add-ons like the Clinical Trial addon very well.

My intuition says that it will be easier for an add-on dev to remove the routes and views that are not needed than to write the boilerplate from scratch.

If this isn't the case, we could always make a more general fork of this repo.
