[Sidefx-houdini-list] Extracting poly edges as a curve

The is a lot of functionality hidden like that.
In the past some of those have been splitted from the original node.
For backward compatibility the features where kept in the original node.
I like using Blast or Ends instead of the Delete or Primitive Sop as 
they feel lighter and make the network more readable.
Still waiting for a Calcutate Normals Sop myself...

Another solution is to create something (toolshelf?) that's called Keep 
Unshared Edges that drops down a Divide Sop with the needed settings.
Maybe some experienced users (who use an Add Sop to delete geometry but 
keep points, actually the Delete Sop can do the same now) could set 
those up.
In the end when you're experienced you'll know where to find these features.
