 When working with the current settings API it's easy to muddle up the
 arguments or miss something out.

 When this happens, there are no fields on the frontend, but aside from
 that, there is no error, no warning, or indication of why the fields
 aren't showing.

 Currently the function `add_settings_field` and similar functions don't
 return a false or error value if they've been misused, e.g. adding a
 setting field to a section that doesn't exist. If it returned a `WP_Error`
 saying so, it would be a lot easier to debug the API
