Rename a variable by its type
Move the edge type detection from drawer into own class
Add addAll and collidesAny collection methods to collision manager
Refactor cut finder to be just cut, change api, find edges too
Make the collision avoiding layout copy the other layout for now
Add an app for testing the collision avoiding layout
Decouple Orthogonal ipe drawing, ipe drawing and String classes
Add a proper interface for orthogonal drawers
Add some missing cleanup to smooth orthogonal drawer
Refactor some drawing stuff in collision avoiding app for profiling
Remove the extra method again
Fix the collision listing method in collision manager
Count the collision while drawing and display a count of graphs with c~
Ignore a file when doing the collision free renders
Fix some stuff for cuts:

* Refactor some common predicates into a helper method
* Find edges for directed graphs as if they were undirected in DFS
* Initialize the left/right edge sets (NPE)
* Handle U edges
* Stay in vertex scope more strictly
* Add some assertions
Work on collision avoidance (open edge geometry, moving up)
