Added initialization of ZV_Qin_dam0 and ZV_Qout_dam0 to zero after allocation otherwise weird values
Added initialization of ZV_Qdam to zero because only values downstream of dams are set by VecSetValues. Added initialization of ZV_Qout_dam_prev to ZV_Qout_dam0 to allow propoer optimization in coupled mode
