--- This module contains the AIRBASE classes.
-- 
-- ===
-- 
-- 1) @{Wrapper.Airbase#AIRBASE} class, extends @{Wrapper.Positionable#POSITIONABLE}
-- =================================================================
-- The @{AIRBASE} class is a wrapper class to handle the DCS Airbase objects:
-- 
--  * Support all DCS Airbase APIs.
--  * Enhance with Airbase specific APIs not in the DCS Airbase API set.
--  
--  
-- 1.1) AIRBASE reference methods
-- ------------------------------ 
-- For each DCS Airbase object alive within a running mission, a AIRBASE wrapper object (instance) will be created within the _@{DATABASE} object.
-- This is done at the beginning of the mission (when the mission starts).
--  
-- The AIRBASE class **does not contain a :New()** method, rather it provides **:Find()** methods to retrieve the object reference
-- using the DCS Airbase or the DCS AirbaseName.
-- 
-- Another thing to know is that AIRBASE objects do not "contain" the DCS Airbase object. 
-- The AIRBASE methods will reference the DCS Airbase object by name when it is needed during API execution.
-- If the DCS Airbase object does not exist or is nil, the AIRBASE methods will return nil and log an exception in the DCS.log file.
--  
-- The AIRBASE class provides the following functions to retrieve quickly the relevant AIRBASE instance:
-- 
--  * @{#AIRBASE.Find}(): Find a AIRBASE instance from the _DATABASE object using a DCS Airbase object.
--  * @{#AIRBASE.FindByName}(): Find a AIRBASE instance from the _DATABASE object using a DCS Airbase name.
--  
-- IMPORTANT: ONE SHOULD NEVER SANATIZE these AIRBASE OBJECT REFERENCES! (make the AIRBASE object references nil).
-- 
-- 1.2) DCS AIRBASE APIs
-- ---------------------
-- The DCS Airbase APIs are used extensively within MOOSE. The AIRBASE class has for each DCS Airbase API a corresponding method.
-- To be able to distinguish easily in your code the difference between a AIRBASE API call and a DCS Airbase API call,
-- the first letter of the method is also capitalized. So, by example, the DCS Airbase method @{Dcs.DCSWrapper.Airbase#Airbase.getName}()
-- is implemented in the AIRBASE class as @{#AIRBASE.GetName}().
-- 
-- More functions will be added
-- ----------------------------
-- During the MOOSE development, more functions will be added.
