Changes since 1.5: +3 -9 lines 
* split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
* move wVel computation at the end of the time step, in S/R integr_continuity
* create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
* update timeave pkg for wVel diagnostic ; put convertEmP2rUnit in PARAMS.h
