These values are used to define square zones for "dynamic spawn system" (spawn randomly around player, the "static spawn system" being intended for fixed places like police station, hospitals...)

NUM CONFIG define how zombies spawn in the zone (how fast, which quantity...) these values are in DynamicSpawnDatas.c file. For example if you set NUM CONFIG to 20 (in DynamicSpawnZones.c) the value from "data_AverageTown" (in DynamicSpawnDatas.c) will be used because its NUMCONFIG is 20 too.

COORDX-upleft / COORDZ-upleft => up left corner of the zone
COORDX-lowerright / COORDZ-lowerright => lower right corner of the zone
"Total Max Zeds Number" is maximum number of zombies in the zone to avoid having 100 zeds in village zones.
"Quantity ratio" is a % applied on the quantity from the DynamicSpawnDatas.c file. It is useful if you want for a big city spawning zombies faster that the other big cities (because all big city use the same config from DynamicSpawnDatas.c)
