The `Median_of_rectangle` and `Median_of_max_spread` are robust sliders that will
neither lead to a linear tree nor to a stack overflow. The `Median_of_rectangle`
splitter will detect if the data in a node is degenerated and applies the
`Median_of_max_spread` rule for that node to avoid a linear tree.
