area-specific growth

Is it feasible to have an area-specific growth effect on all morphs while in an area.

When fish of a given morph move to a different area, the mean size of fish of that morph in the recipient area becomes the weighted average of fish of that morph already in the area and the size of fish entering the area.

So do a calculation like that for the plus group.

Thank you Andre for this thought.

comment from @RickMethot on 2020-03-16: Begin brainstorming implementation issues:

Right now, size-at-age is indexed by morph and N-at-age is indexed by morph and by area: 4darray Ave_Size(styr-3nseas,TimeMax_Fcast_std+nseas,1,N_subseas,1,gmorph,0,nages) 4darray natage(styr-3nseas,TimeMax_Fcast_std+nseas,1,pop,1,gmorph,0,nages)

An easy implementation scenario is to define just one morph for each area when using this option.
