- BendNetwork.find_crossings()
 Identify all pairs of crossing edges in a graph.
- Parameters:
 - graph
compas.datastructures.Graph A graph object.
- graph
 - Returns:
 - list[tuple[tuple[hashable, hashable], tuple[hashable, hashable]]]
 A list of edge pairs, with each edge represented by two vertex keys.
Notes
This algorithm assumes that the graph lies in the XY plane.
