Make moving sets upwards work and adjust cur for this
Add a grapg where a set must be moved up to the interesting graphs
Add reasons to list of interesting graphs
Collect names of graphs with collisions instead of just counting
Rename collision domain to body, add some comments
Fix handling of U edges in cut (disconnected vertices in some cases)
Adjust slope of side L edges too
Refactor some stuff into methods in collision avoiding layout
Add slope adjusting of bottom incoming L edges
Add another graph to interesting graphs (one that gets huuuuge)
Add some other two not-so-planar graphs to ignore list
Avoid collisions with L edges at bottom port too
Fix a debug message
Adjust drawing positioning to fit the Ipe editor's 16pt grid
When resetting the collision layout, reset the parent layout too
Add the escalation level to the collision avoiding layout
