66 Lyckades köra JavaMonWeb i Debug läge med Tomcat 7 local server. Skapade en sanityCheck() metod med break points så jag kan debugga när vissa räknare blir negativa.
67 Dock svårt att hitta rätt LongDelta objekt, eftersom det finns över 1000 i listan i random ordning. Behöver spara undan det nånstans eller breaka inne i en LongDelta metod istället.
68 Checkar in detta i alla fall så länge.
