quality control vessel airways in viewer

[deiluca]

The idea is to provide a guided semi-automated approach to disconnect vessels and airways in the skeleton graph.

1. A script identifies parallel edge pairs in the graph with low distance and low angle. These are candidate vessel-airway overlap locations. A first JSON file with these locations is provided here: /links/groups/iber/Projects/Lung_Fractalization/human_organ_atlas/vessel_airway_separation/connecting_paths.json. Just intended for testing, it is just run on a graph subset.
2. Load the JSON in the Skeleplex Viewer to browse the locations (left panel - Data Stores - Edge Coloring) and press Run.
3. The code automatically computes the shortest connecting path between the first edge pair. It visualize the parallel edges in red, the connecting path in green, and the surrounding edges in blue (segmentation overlay optional).
4. Iteratively click through candidate vessel-airway locations (right panel bottom - Edge Coloring Navigator) and manually delete the problematic edges/nodes until the airways and vessels are two separate graphs. After each edge deletion the shortest path is recalculated and the bounding box is re-rendered.
