PhaseJumpDetection3D
Bases: RotorDetection
Implements phase jump method of rotor detection on 3D irregular meshes.
Given sorted neighbor rings, calculates the amount of odd phasejumps in each ring and classifies these points as Phase Singularity points. Phasejumps are defined as differences in neighboring phases larger than a threshold. Based on: doi: 10.3414/me0427

__init__(phases)
calc_neighbor_rings(coords, edges, radius)
Indices of clockwise sorted points on ring i < n_rings around node j < N. Shape of each array is (N, n_ring_points).
detect()
Calculate phase singularities defined as loops containing a summed phase difference between neighboring points, restricted to [-pi, pi], equal to ±2kpi where k != 0.
