kts.GetTiles – get a list of tiles in a given dungeon square
result = kts.GetTiles(params)
Given a dungeon position, returns a list of all Tiles currently at that location.
A Lua list/array, containing zero or more Tile userdata objects, is returned.
An error is raised if the given position is invalid.
Recall that each dungeon square can contain zero or more Tiles, but typically there would be around one to two tiles per square (an example might be a floor tile with a treasure chest on top of it).
