=== Datum ===

Datums have the smallest number of pre-defined variables. These are present in all objects in the game:
  type //The type of an object. If your object is of type /obj/item/weapon/shovel writing the following: new src.type(src.loc) will make another shovel in the same tile.
  parent_type //Parent type of /obj/item/weapon/shovel is /obj/item/weapon... seems streight-foward enough.
  tag //The tag is used to help you identify things when using several instances. It has to be set manually for each instance tho. Lazy coders and mappers resulted in not many tags being used. Instances in the map editor are sorted by tag.
  vars //List of object vars the datum has defined
