its id (position in the grid) its current generations, next migrating individual, etc...
Register the first best this server has seen, if something already in database then
assume this run is being resumed and the best in database is up to date.
A snapshot painter is capable of providing a graphical version of something related
to the current evolutionary process, such as a diagram of the current elite individual.
