Real Pipes/Tubes Geometry nodes in Blender

This is a node group that creates pipes (tubes) from curves. Sounds like not that big of a deal, but if You watch this showcase video https://youtu.be/odEh4RrWh50, you'll understand why IT IS A BIG DEAL :)

Blender out of the box creates tubes from curves in a very bad way, deforming the thickness of the pipe (tube) based on the angle between two edges. This node corrects this behavior
...and it also creates wireframes from meshes.
