+Maps are saved in maps directory with json format.\
+It's two dimensional array of types of fields. \

+  ["Clay", "Soil","Clay"],
+  ["Sunflower", "Soil","Corn"]

+#####4.1 Save generated map:

+Map will be saved in maps directory.

+#####4.2 Load map
+```bash
+python main.py --load-map=name_of_map
+```
+Map must be in the maps directory with json extension.
