[Sidefx-houdini-list] point -> edge list

I think this is a long-standing RFE.

You can find an Hscript expression-based way that works with ordered 
point groups here:

There's an HDK-based approach here:

I did this myself recently deep inside an OTL when I needed a procedural 
Dissolve, and came up with a minor monstrosity involving inline VEX, the 
"getneighbours" function, and a Python expression (it's faster than it 
sounds).  I don't think the list supports attachments, so see here:

This would be pretty easy to turn into an OTL, and with Python sets and 
a neighbours list you can come up with any combination of open/closed 
edges, etc.

Hope this helps
