* AMF Classifier & Mondrian Tree Classifier implementation

* [Pull request Update]
- Adding a "mondrian" folder in the "tree" folder for better file structure
- Using "random.choices" instead of the "sample_discrete" functions in "utils.py", and removing "sample_discrete" from the "utils.py"

* [Pull Request]
- Removing the "__repr__" method of AMF
- Removing the @Setter and @getter
- Removing the "loss" parameter of the classifiers since only the "log-loss" is being used in the end

* Updating docstring

* [Pull request]
- Making `learn_one` and `predict_proba_one` accepting all kinds of supported labels for `y` as input
- `predict_proba_one` outputs a dictionary of scores with matching labels
