   The 16 digit ID of nodes and edges is generated by applying certain masking algorithm on the ID of label associated with that node/edge. Since the labels are actually tables that store the nodes/edges associated to them in that table and the ID of these tables are generated by a sequence (you can find the ID of a label table using `SELECT * FROM ag_label` --> This outputs a column named id that is basically the label ID I am talking about.) 
   In order to actually see how the IDs are given to nodes/edges, debug a simple CREATE statement with breakpoints on 
   
   1. create_vertex
   2. ExecEvalExpr
   
   This will give you a more clear picture
   Hope it helps!
