Profession system

how do it work? (will work (maybe (maybe)))

professions are stored as a graph. edge a -> b represents ability to change profession from a to b and have additional parameter representing how hard to switch from a to b. each profession has it's capacity (maximum possible sum of sizes of agents that have this profession). capacity provided by enterprises and represents job opportunities for agents. there are two sets of rules: rules for pops and rules for character.

current implementation

pop have more savings -> other pops move to it if possible
