+0) assimilation of two simple synthetic observations works as expected.
+1) innovation observation file conversion supported. Have not run it through filter.
+   those forward operators are appropriate for the existing obs_def_navdas_mod.f90,
+   apparently has potential temperature as part of the state. Do we want to convert
+   potential temperature to sensible temperature up-front - so we can use any/all other
+   DART observation converters? Would require converting back after assimilation.
+2) creating an initial ensemble ... TBD ... Tim W. had several ideas on how to perturb
+   a single state to generate an ensemble.  ball is in NRL's hands.
+3) Not sure how to test vertical conversion ... (re-engage Nancy?)
+4) Firm up the mechanism to convey the fcstfld being read and then updating the analfld 
+   to be used as the starting point for the next forecast cycle.  Sergey indicated an
