-import/export functionality is mostly based
-on Bart Crouch's Theme Manager Addon

-TODO: quadview complete support : investigate. Where's the data?
-TODO: lock_camera_and_layers. investigate usage
-TODO: list reordering
-
-NOTE: logging setup has to be provided by the user in a separate config file
-    as Blender will not try to configure logging by default in an add-on
-    The Config File should be in the Blender Config folder > /scripts/startup/config_logging.py
-    For setting up /location of the config folder see:
-    https://docs.blender.org/manual/en/dev/getting_started/
-    installing/configuration/directories.html
-    For configuring logging itself in the file, general Python documentation should work
-    As the logging calls are not configured, they can be kept in the other modules of this add-on
-    and will not have output until the logging configuration is set up
