 - Important performance fix if model does vertical conversion for localization.
-Results were not wrong but performance was poor if 'distribute_mean = .true.' 
-was selected in the &assim_tools_nml namelist.
-Now distributing the mean runs in close to the non-distributed time and uses
-much less memory for large models. This only impacts models which do a vertical
-conversion of either the observation or state vertical coordinate for localization
-AND which set &assim_tools_nml :: distribute_mean = .true. to use less memory.
-When using a distributed mean "convert_all_obs_verticals_first = .true." should 
-be set.  If your observations will impact most of the model state, then 
-"convert_all_state_verticals_first = .true.' can also be set.
