This class represents the embedding tree of a single node in a biconnected component.
The embedding tree is a PCTree with one leaf for each incident edge that describes all possible rotations of the incident edges in all planar embeddings of the component. Uses the Booth&Lueker Planarity Test for computing the embedding tree, see https://doi.org/10.15475/cpatp.2024 (Section 9.2).
