Various refactoring and shaping of the FB_Edge_Of_Network_Node methods to
DBSeq is for DEATH/BIRTH especially;
LWT_NDEATH => BdSeq 0 (tally up 1 with each death/birth so 1,2,3, etc)
NBIRTH <= BdSeq = LWT_NDEATH.BdSeq,
Seq = 0(!)
Every subsequent NDATA, DBIRTH, DDEATH and DDATA uses Seq = Seq+1 MOD 256
