subroutine FIZHI_WRAPPER (myTime, myIter, myThid)
c-----------------------------------------------------------------------
c Subroutine fizhi_wrapper - 'Wrapper' routine to interface
c with physics driver.
c 1) Set up "bi, bj loop" and some timers and clocks.
c 2) Call do_fizhi - driver for physics which computes tendencies
c 3) Interpolate tendencies to dynamics grid in vertical
c 4) Convert u,v tendencies to C-Grid
c
c Calls: do_fizhi (get u,v,t,s tend, step tke, etc and tc, etc. forward)
c phys2dyn (4 calls - all physics tendencies)
c AtoC (u and v tendencies)
