Please explain to me what you mean with city_map and igter_move. Is
city_map a warmap which is created out of a city?

This isn't about moves but about turns. I want information like "the
settler with id 4 will arrive at (4,5) in at most 5 turns and there
will have 1/3 moves left (so it can start build the road at this
turn)". Even better would be "and the settler can achieve the same
distance in 3 turns if it has luck".

What about conformance to other civs?
