/proc/get_dist(/atom/Loc1, /atom/Loc2)
Arguments:
Loc1 (/atom): An object on the map.
Loc2 (/atom): An object on the map.
Returns:
num: The number of tiles between both arguments.

If either object is not on the map, 127 will be returned. If both arguments are the same object, -1 will be returned.

Parity Issue ⚠️
In the OpenDream implementation of DreamMaker, this feature differs in implementation:
In BYOND, the distance in Z level is also calculated.
