--- This module contains the CONTROLLABLE class.
-- 
-- 1) @{Controllable#CONTROLLABLE} class, extends @{Positionable#POSITIONABLE}
-- ===========================================================
-- The @{Controllable#CONTROLLABLE} class is a wrapper class to handle the DCS Controllable objects:
--
--  * Support all DCS Controllable APIs.
--  * Enhance with Controllable specific APIs not in the DCS Controllable API set.
--  * Handle local Controllable Controller.
--  * Manage the "state" of the DCS Controllable.
--
-- 1.1) CONTROLLABLE constructor
-- -----------------------------
-- The CONTROLLABLE class provides the following functions to construct a CONTROLLABLE instance:
--
--  * @{#CONTROLLABLE.New}(): Create a CONTROLLABLE instance.
--
-- 1.2) CONTROLLABLE task methods
-- ------------------------------
-- Several controllable task methods are available that help you to prepare tasks. 
-- These methods return a string consisting of the task description, which can then be given to either a @{Controllable#CONTROLLABLE.PushTask} or @{Controllable#SetTask} method to assign the task to the CONTROLLABLE.
-- Tasks are specific for the category of the CONTROLLABLE, more specific, for AIR, GROUND or AIR and GROUND. 
-- Each task description where applicable indicates for which controllable category the task is valid.
-- There are 2 main subdivisions of tasks: Assigned tasks and EnRoute tasks.
-- 
-- ### 1.2.1) Assigned task methods
-- 
-- Assigned task methods make the controllable execute the task where the location of the (possible) targets of the task are known before being detected.
-- This is different from the EnRoute tasks, where the targets of the task need to be detected before the task can be executed.
-- 
-- Find below a list of the **assigned task** methods:
-- 
--   * @{#CONTROLLABLE.TaskAttackGroup}: (AIR) Attack a Controllable.
--   * @{#CONTROLLABLE.TaskAttackMapObject}: (AIR) Attacking the map object (building, structure, e.t.c).
--   * @{#CONTROLLABLE.TaskAttackUnit}: (AIR) Attack the Unit.
--   * @{#CONTROLLABLE.TaskBombing}: (AIR) Delivering weapon at the point on the ground.
--   * @{#CONTROLLABLE.TaskBombingRunway}: (AIR) Delivering weapon on the runway.
--   * @{#CONTROLLABLE.TaskEmbarking}: (AIR) Move the controllable to a Vec2 Point, wait for a defined duration and embark a controllable.
--   * @{#CONTROLLABLE.TaskEmbarkToTransport}: (GROUND) Embark to a Transport landed at a location.
--   * @{#CONTROLLABLE.TaskEscort}: (AIR) Escort another airborne controllable. 
--   * @{#CONTROLLABLE.TaskFAC_AttackGroup}: (AIR + GROUND) The task makes the controllable/unit a FAC and orders the FAC to control the target (enemy ground controllable) destruction.
--   * @{#CONTROLLABLE.TaskFireAtPoint}: (GROUND) Fire some or all ammunition at a VEC2 point.
--   * @{#CONTROLLABLE.TaskFollow}: (AIR) Following another airborne controllable.
--   * @{#CONTROLLABLE.TaskHold}: (GROUND) Hold ground controllable from moving.
--   * @{#CONTROLLABLE.TaskHoldPosition}: (AIR) Hold position at the current position of the first unit of the controllable.
--   * @{#CONTROLLABLE.TaskLand}: (AIR HELICOPTER) Landing at the ground. For helicopters only.
--   * @{#CONTROLLABLE.TaskLandAtZone}: (AIR) Land the controllable at a @{Zone#ZONE_RADIUS).
--   * @{#CONTROLLABLE.TaskOrbitCircle}: (AIR) Orbit at the current position of the first unit of the controllable at a specified alititude.
--   * @{#CONTROLLABLE.TaskOrbitCircleAtVec2}: (AIR) Orbit at a specified position at a specified alititude during a specified duration with a specified speed.
--   * @{#CONTROLLABLE.TaskRefueling}: (AIR) Refueling from the nearest tanker. No parameters.
--   * @{#CONTROLLABLE.TaskRoute}: (AIR + GROUND) Return a Misson task to follow a given route defined by Points.
--   * @{#CONTROLLABLE.TaskRouteToVec2}: (AIR + GROUND) Make the Controllable move to a given point.
--   * @{#CONTROLLABLE.TaskRouteToVec3}: (AIR + GROUND) Make the Controllable move to a given point.
--   * @{#CONTROLLABLE.TaskRouteToZone}: (AIR + GROUND) Route the controllable to a given zone.
--   * @{#CONTROLLABLE.TaskReturnToBase}: (AIR) Route the controllable to an airbase.
--
-- ### 1.2.2) EnRoute task methods
-- 
-- EnRoute tasks require the targets of the task need to be detected by the controllable (using its sensors) before the task can be executed:
-- 
--   * @{#CONTROLLABLE.EnRouteTaskAWACS}: (AIR) Aircraft will act as an AWACS for friendly units (will provide them with information about contacts). No parameters.
--   * @{#CONTROLLABLE.EnRouteTaskEngageControllable}: (AIR) Engaging a controllable. The task does not assign the target controllable to the unit/controllable to attack now; it just allows the unit/controllable to engage the target controllable as well as other assigned targets.
--   * @{#CONTROLLABLE.EnRouteTaskEngageTargets}: (AIR) Engaging targets of defined types.
--   * @{#CONTROLLABLE.EnRouteTaskEWR}: (AIR) Attack the Unit.
--   * @{#CONTROLLABLE.EnRouteTaskFAC}: (AIR + GROUND) The task makes the controllable/unit a FAC and lets the FAC to choose a targets (enemy ground controllable) around as well as other assigned targets.
--   * @{#CONTROLLABLE.EnRouteTaskFAC_EngageControllable}: (AIR + GROUND) The task makes the controllable/unit a FAC and lets the FAC to choose the target (enemy ground controllable) as well as other assigned targets.
--   * @{#CONTROLLABLE.EnRouteTaskTanker}: (AIR) Aircraft will act as a tanker for friendly units. No parameters.
-- 
-- ### 1.2.3) Preparation task methods
-- 
-- There are certain task methods that allow to tailor the task behaviour:
--
--   * @{#CONTROLLABLE.TaskWrappedAction}: Return a WrappedAction Task taking a Command.
--   * @{#CONTROLLABLE.TaskCombo}: Return a Combo Task taking an array of Tasks.
--   * @{#CONTROLLABLE.TaskCondition}: Return a condition section for a controlled task.
--   * @{#CONTROLLABLE.TaskControlled}: Return a Controlled Task taking a Task and a TaskCondition.
-- 
-- ### 1.2.4) Obtain the mission from controllable templates
-- 
-- Controllable templates contain complete mission descriptions. Sometimes you want to copy a complete mission from a controllable and assign it to another:
-- 
--   * @{#CONTROLLABLE.TaskMission}: (AIR + GROUND) Return a mission task from a mission template.
--
-- 1.3) CONTROLLABLE Command methods
-- --------------------------
-- Controllable **command methods** prepare the execution of commands using the @{#CONTROLLABLE.SetCommand} method:
-- 
--   * @{#CONTROLLABLE.CommandDoScript}: Do Script command.
--   * @{#CONTROLLABLE.CommandSwitchWayPoint}: Perform a switch waypoint command.
-- 
-- 1.4) CONTROLLABLE Option methods
-- -------------------------
-- Controllable **Option methods** change the behaviour of the Controllable while being alive.
-- 
-- ### 1.4.1) Rule of Engagement:
-- 
--   * @{#CONTROLLABLE.OptionROEWeaponFree} 
--   * @{#CONTROLLABLE.OptionROEOpenFire}
--   * @{#CONTROLLABLE.OptionROEReturnFire}
--   * @{#CONTROLLABLE.OptionROEEvadeFire}
-- 
-- To check whether an ROE option is valid for a specific controllable, use:
-- 
--   * @{#CONTROLLABLE.OptionROEWeaponFreePossible} 
--   * @{#CONTROLLABLE.OptionROEOpenFirePossible}
--   * @{#CONTROLLABLE.OptionROEReturnFirePossible}
--   * @{#CONTROLLABLE.OptionROEEvadeFirePossible}
-- 
-- ### 1.4.2) Rule on thread:
-- 
--   * @{#CONTROLLABLE.OptionROTNoReaction}
--   * @{#CONTROLLABLE.OptionROTPassiveDefense}
--   * @{#CONTROLLABLE.OptionROTEvadeFire}
--   * @{#CONTROLLABLE.OptionROTVertical}
-- 
-- To test whether an ROT option is valid for a specific controllable, use:
-- 
--   * @{#CONTROLLABLE.OptionROTNoReactionPossible}
--   * @{#CONTROLLABLE.OptionROTPassiveDefensePossible}
--   * @{#CONTROLLABLE.OptionROTEvadeFirePossible}
--   * @{#CONTROLLABLE.OptionROTVerticalPossible}

-- TASKS FOR AIR CONTROLLABLES


--- (AIR) Attack a Controllable.
-- @param #CONTROLLABLE self
-- @param Wrapper.Controllable#CONTROLLABLE AttackGroup The Controllable to be attacked.
-- @param #number WeaponType (optional) Bitmask of weapon types those allowed to use. If parameter is not defined that means no limits on weapon usage.
-- @param Dcs.DCSTypes#AI.Task.WeaponExpend WeaponExpend (optional) Determines how much weapon will be released at each attack. If parameter is not defined the unit / controllable will choose expend on its own discretion.
-- @param #number AttackQty (optional) This parameter limits maximal quantity of attack. The aicraft/controllable will not make more attack than allowed even if the target controllable not destroyed and the aicraft/controllable still have ammo. If not defined the aircraft/controllable will attack target until it will be destroyed or until the aircraft/controllable will run out of ammo.
-- @param Dcs.DCSTypes#Azimuth Direction (optional) Desired ingress direction from the target to the attacking aircraft. Controllable/aircraft will make its attacks from the direction. Of course if there is no way to attack from the direction due the terrain controllable/aircraft will choose another direction.
-- @param Dcs.DCSTypes#Distance Altitude (optional) Desired attack start altitude. Controllable/aircraft will make its attacks from the altitude. If the altitude is too low or too high to use weapon aircraft/controllable will choose closest altitude to the desired attack start altitude. If the desired altitude is defined controllable/aircraft will not attack from safe altitude.
-- @param #boolean AttackQtyLimit (optional) The flag determines how to interpret attackQty parameter. If the flag is true then attackQty is a limit on maximal attack quantity for "AttackGroup" and "AttackUnit" tasks. If the flag is false then attackQty is a desired attack quantity for "Bombing" and "BombingRunway" tasks.
