- Added `CORE_FOLDER` and `API_FOLDER` settings in order to organize code and separate concerns in our APIs:

py
CORE_FOLDER = "my_core_folder_path/" you can leave them empty
API_FOLDER = "my_api_folder_path/" or set them to be the same


- Core folder is for `models.py` `admin.py` and `migrations`
- API folder will contain `views.py` `serializers.py` and `urls.py`

- minor typo fix with URLs

- Major changes and improvements 👍🏻
