(remember we need to keep the old as the basis, and things can change, the db is not consistent anymore then ....)
But we also dont want useless refereces ......
TODO: solution,
ALSO:
Update the 2 references tables: all state paths get: Path statepath --> List(int revnumber, List(References))
TODO EDIT TABLES references,references_state,referrers,referrers_state
Update the 2 references tables:
all state paths get: run number + state references + revision numbers) THIS ONE !!!!!!
New table stateRevisionClosure: Path StatePath + int revision --> List(int revnumbers)
A1(STATEPATH) --> UPDATE ALL STATE REFERENCES IN DB (TRANSACTION)
A2(STATEPATH [+ REV]) --> GIVE ALL STATE REFERENCES IN DB
