In settings.py file, the paths to the data root directories for all the susi datasets are set. If the path cannot be found locally, a warning is generated that the data will be read from the network drives.
The goal of this hotfix is to limit the generation of the warning to only the case when a data root is used.
A new class DataDirs will be created, and the data root can be acquired using a __get_item__(env_name) function.
