objective_holder

An objective holder for minds, antag datums, and teams.

Vars
assigned_targets	A list of strings which contain targets of the antagonist's objectives. Used to prevent duplicate objectives.
objective_owner	Who do we belong to [mind, antagonist, team]
objectives	Our list of current objectives
on_add_callback	A callback invoked when a new objective is added. This is required because sometimes objectives are added directly without going through objective_owner. Not currently used.
on_remove_callback	A callback invoked when a new objective is added. This is required because sometimes objectives are removed directly without going through objective_owner (EX: replace_objective(), clear()). Not currently used.
Procs
add_objective	Add an objective.
clear	Clear all objectives of a certain type
get_objectives	Get all of the objectives we own
handle_objective	Handles the searching of targets for objectives that need it.
has_objectives	Do we have any objectives
remove_objective	Remove an objective and deletes it. You should never need to transfer an objective.
replace_objective	Replace old_objective with new_objective
set_callbacks	Sets the callbacks, not on new because that can be irreliable for subtypes.
