--- This module contains the IDENTIFIABLE class.
-- 
-- 1) @{#IDENTIFIABLE} class, extends @{Wrapper.Object#OBJECT}
-- ===============================================================
-- The @{#IDENTIFIABLE} class is a wrapper class to handle the DCS Identifiable objects:
--
--  * Support all DCS Identifiable APIs.
--  * Enhance with Identifiable specific APIs not in the DCS Identifiable API set.
--  * Manage the "state" of the DCS Identifiable.
--
-- 1.1) IDENTIFIABLE constructor:
-- ------------------------------
-- The IDENTIFIABLE class provides the following functions to construct a IDENTIFIABLE instance:
--
--  * @{#IDENTIFIABLE.New}(): Create a IDENTIFIABLE instance.
--
-- 1.2) IDENTIFIABLE methods:
-- --------------------------
-- The following methods can be used to identify an identifiable object:
-- 
--    * @{#IDENTIFIABLE.GetName}(): Returns the name of the Identifiable.
--    * @{#IDENTIFIABLE.IsAlive}(): Returns if the Identifiable is alive.
--    * @{#IDENTIFIABLE.GetTypeName}(): Returns the type name of the Identifiable.
--    * @{#IDENTIFIABLE.GetCoalition}(): Returns the coalition of the Identifiable.
--    * @{#IDENTIFIABLE.GetCountry}(): Returns the country of the Identifiable.
--    * @{#IDENTIFIABLE.GetDesc}(): Returns the descriptor structure of the Identifiable.
