Create a notebook where parts of the row dimension MultiIndex become features #23
Description
@gpfreitas Made the point today that the examples in ./notebooks with MLDataset.to_features() do not show using the dimension related information in the features. It shows calling to_features to create a MultiIndex.
Add an example a custom transformer function extracts from the MultiIndex the dimension related info, e.g. lat, lon, time, and does some binning operation on those dimension related data to create additional features
