=== next
Get the next object in the object chain.
When called without an object, returns the first object in the object chain.
When called with an object, an optional boolean parameter can be given. When
it is true, and the object is on the map, the next object at the same location
is returned. Otherwise the normal object chain is followed.
Example:
local o = obj.at(x, y);
local o2 = o:next();
local first = obj.next();
local second = first:next();
local o_at_xy = obj.at(x, y);
local next_at_xy = o_at_xy:next(true);
