New experiments/medial_tire_cut_labelling.py: takes a full medial tire graph and an entry up tooth and runs the walk-depth labelling-and-cut procedure, reusing the full medial tire generator's model and emitting TikZ. Add a generator-produced 8-tooth example to the paper (Figure 1, Example 2.3) showing the labelling and the two cuts, plus a remark fixing the cut's closing tooth for descended faces.
