Sverchok Node Tree Updates needlessly

Created by: wassimj

Problem statement

With the latest version of sverchok, it seems anytime I connect a new node, existing nodes that are on a separate unrelated branch get updated which slows down all execution.

For any other issues, or if the installation still failed; Please describe the problem here.

Steps to reproduce

1. Create a node tree that is time consuming to complete
2. Add a new node and connetc

Expected result

Only the affected/downstream nodes to be updated

Actual result

Unrelated nodes get updated.
