--- @type IDENTIFIABLE
-- @extends Wrapper.Object#OBJECT
-- @field #string IdentifiableName The name of the identifiable.

--- 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.

-- ## IDENTIFIABLE constructor

--
--  * @{#IDENTIFIABLE.New}(): Create a IDENTIFIABLE instance.
