`math_utils.py` is in the root code folder. This creates the `langchain.math_utils: Math Utils` group on the API Reference navigation ToC, on the same level with `Chains` and `Agents` which is not correct. Refactoring: - created the `utils/` folder - moved `math_utils.py` to `utils/math.py` - moved `utils.py` to `utils/utils.py` - split `utils.py` into `utils.py, env.py, strings.py` - added module description @baskaryan
