--- This module contains the AIBALANCER class.
--
-- ===
--
-- 1) @{Functional.AIBalancer#AIBALANCER} class, extends @{Core.Base#BASE}
-- =======================================================
-- The @{Functional.AIBalancer#AIBALANCER} class controls the dynamic spawning of AI GROUPS depending on a SET_CLIENT.
-- There will be as many AI GROUPS spawned as there at CLIENTS in SET_CLIENT not spawned.
-- The AIBalancer uses the @{PatrolCore.Zone#PATROLZONE} class to make AI patrol an zone until the fuel treshold is reached.
--
-- 1.1) AIBALANCER construction method:
-- ------------------------------------
-- Create a new AIBALANCER object with the @{#AIBALANCER.New} method:
--
-- * @{#AIBALANCER.New}: Creates a new AIBALANCER object.
--
-- 1.2) AIBALANCER returns AI to Airbases:
-- ---------------------------------------
-- You can configure to have the AI to return to:
--
-- * @{#AIBALANCER.ReturnToHomeAirbase}: Returns the AI to the home @{Wrapper.Airbase#AIRBASE}.
-- * @{#AIBALANCER.ReturnToNearestAirbases}: Returns the AI to the nearest friendly @{Wrapper.Airbase#AIRBASE}.
--
-- 1.3) AIBALANCER allows AI to patrol specific zones:
-- ---------------------------------------------------
-- Use @{Functional.AIBalancer#AIBALANCER.SetPatrolZone}() to specify a zone where the AI needs to patrol.
--

-- **API CHANGE HISTORY**
-- ======================
--
-- The underlying change log documents the API changes. Please read this carefully. The following notation is used:
--
-- * **Added** parts are expressed in bold type face.
-- * _Removed_ parts are expressed in italic type face.
--
-- Hereby the change log:
--
-- 2016-08-17: SPAWN:**InitCleanUp**( SpawnCleanUpInterval ) replaces SPAWN:_CleanUp_( SpawnCleanUpInterval )
--
-- * Want to ensure that the methods starting with **Init** are the first called methods before any _Spawn_ method is called!
-- * This notation makes it now more clear which methods are initialization methods and which methods are Spawn enablement methods.
--
-- ===
--
-- AUTHORS and CONTRIBUTIONS
-- =========================
--
-- ### Contributions:
--
-- * **Dutch_Baron (James)**: Who you can search on the Eagle Dynamics Forums.
-- Working together with James has resulted in the creation of the AIBALANCER class.
-- James has shared his ideas on balancing AI with air units, and together we made a first design which you can use now :-)
--
-- * **SNAFU**:
-- Had a couple of mails with the guys to validate, if the same concept in the GCI/CAP script could be reworked within MOOSE.
-- None of the script code has been used however within the new AIBALANCER moose class.
