* Trains a network on the scikit-learn [iris](https://scikit-learn.org/stable/modules/generated/sklearn.datasets.load_iris.html#sklearn.datasets.load_iris)
classification dataset using XGBoost
* Scores accuracy using scikit-learn
* ClearML automatically logs the input model registered by XGBoost, and the output model (and its checkpoints),
feature importance plot, and tree plot created with XGBoost.
* Creates an experiment named `XGBoost simple example`, which is associated with the `examples` project.
