--- **Tasking** - This module contains the DETECTION_MANAGER class and derived classes.
-- 
-- ===
-- 
-- The @{#DETECTION_MANAGER} class defines the core functions to report detected objects to groups.
-- Reportings can be done in several manners, and it is up to the derived classes if DETECTION_MANAGER to model the reporting behaviour.
-- 
-- ![Banner Image](..\Images\deprecated.png)
-- 
-- 1.1) DETECTION_MANAGER constructor:
-- -----------------------------------
--   * @{#DETECTION_MANAGER.New}(): Create a new DETECTION_MANAGER instance.
-- 
-- 1.2) DETECTION_MANAGER reporting:
-- ---------------------------------
-- Derived DETECTION_MANAGER classes will reports detected units using the method @{#DETECTION_MANAGER.ReportDetected}(). This method implements polymorphic behaviour.
-- 
-- The time interval in seconds of the reporting can be changed using the methods @{#DETECTION_MANAGER.SetRefreshTimeInterval}(). 
-- To control how long a reporting message is displayed, use @{#DETECTION_MANAGER.SetReportDisplayTime}().
-- Derived classes need to implement the method @{#DETECTION_MANAGER.GetReportDisplayTime}() to use the correct display time for displayed messages during a report.
-- 
-- Reporting can be started and stopped using the methods @{#DETECTION_MANAGER.StartReporting}() and @{#DETECTION_MANAGER.StopReporting}() respectively.
-- If an ad-hoc report is requested, use the method @{#DETECTION_MANAGER.ReportNow}().
-- 
-- The default reporting interval is every 60 seconds. The reporting messages are displayed 15 seconds.
-- 
-- ===
-- 
-- 2) @{#DETECTION_REPORTING} class, extends @{#DETECTION_MANAGER}
-- ===
-- The @{#DETECTION_REPORTING} class implements detected units reporting. Reporting can be controlled using the reporting methods available in the @{Tasking.DetectionManager#DETECTION_MANAGER} class.
-- 
-- 2.1) DETECTION_REPORTING constructor:
-- -------------------------------
-- The @{#DETECTION_REPORTING.New}() method creates a new DETECTION_REPORTING instance.
--    
--
-- # Developer Note
-- 
-- Note while this class still works, it is no longer supported as the original author stopped active development of MOOSE
-- Therefore, this class is considered to be deprecated
