+            # For some preknowledge:

+            # the same position on the UV map, then it considers it one point and the user can move it

+            #

+            # The problem is that the data for whether the uv corners of two faces that share a vertex physically being connected and selected as one vertex on the uv map does not exist

+            # allowing for the moving of vertices of 4 faces connected by a single vertex. Behavior every normal blender user is familiar with. 
+            # 
+            # The solution
+            # We can use this to our advantage, by finding vertices on the uv map that share the same coridinate as another vertex that is also selected.
+            # that way we can group each pair shared in a line as the same vertex, and identify the line using these pairs and using the data that says for certain
