--- **Core** - Informs the players using messages during a simulation.
--
-- ===
--
-- ## Features:
--
--   * A more advanced messaging system using the DCS message system.
--   * Time messages.
--   * Send messages based on a message type, which has a pre-defined duration that can be tweaked in SETTINGS.
--   * Send message to all players.
--   * Send messages to a coalition.
--   * Send messages to a specific group.
--   * Send messages to a specific unit or client.

--- The MESSAGE class
-- @type MESSAGE
-- @extends Core.Base#BASE

--- Message System to display Messages to Clients, Coalitions or All.
-- Messages are shown on the display panel for an amount of seconds, and will then disappear.
-- Messages can contain a category which is indicating the category of the message.
--
-- ## MESSAGE construction
--
-- Messages are created with @{#MESSAGE.New}. Note that when the MESSAGE object is created, no message is sent yet.
-- To send messages, you need to use the To functions.
--
-- ## Send messages to an audience
--
-- Messages are sent:
--
--   * To a @{Wrapper.Client} using @{#MESSAGE.ToClient}().
--   * To a @{Wrapper.Group} using @{#MESSAGE.ToGroup}()
--   * To a @{Wrapper.Unit} using @{#MESSAGE.ToUnit}()
--   * To a coalition using @{#MESSAGE.ToCoalition}().
--   * To the red coalition using @{#MESSAGE.ToRed}().
--   * To the blue coalition using @{#MESSAGE.ToBlue}().
--   * To all Players using @{#MESSAGE.ToAll}().
--
-- ## Send conditionally to an audience
--
-- Messages can be sent conditionally to an audience (when a condition is true):
--
--   * To all players using @{#MESSAGE.ToAllIf}().
--   * To a coalition using @{#MESSAGE.ToCoalitionIf}().
