--- **Core** - The base class within the framework.
--
-- ===
--
-- ## Features:
--
--   * The construction and inheritance of MOOSE classes.
--   * The class naming and numbering system.
--   * The class hierarchy search system.
--   * The tracing of information or objects during mission execution for debugging purposes.
--   * The subscription to DCS events for event handling in MOOSE objects.
--   * Object inspection.
--
-- ===
--
-- All classes within the MOOSE framework are derived from the BASE class.
-- Note: The BASE class is an abstract class and is not meant to be used directly.

--- @type BASE
-- @field ClassName The name of the class.
-- @field ClassID The ID number of the class.
-- @field ClassNameAndID The name of the class concatenated with the ID number of the class.

--- BASE class
--
-- # 1. BASE constructor.
--
-- Any class derived from BASE, will use the @{Core.Base#BASE.New} constructor embedded in the @{Core.Base#BASE.Inherit} method.
-- See an example at the @{Core.Base#BASE.New} method how this is done.
--
-- # 2. Trace information for debugging.
--
-- The BASE class contains trace methods to trace progress within a mission execution of a certain object.
-- These trace methods are inherited by each MOOSE class inheriting BASE, thus all objects created from
-- a class derived from BASE can use the tracing methods to trace its execution.
--
-- Any type of information can be passed to these tracing methods. See the following examples:
--
--     self:E( "Hello" )
--
-- Result in the word "Hello" in the dcs.log.
--
--     local Array = { 1, nil, "h", { "a","b" }, "x" }
--     self:E( Array )
--
-- Results with the text [1]=1,[3]="h",[4]={[1]="a",[2]="b"},[5]="x"} in the dcs.log.
--
--     local Object1 = "Object1"
--     local Object2 = 3
--     local Object3 = { Object 1, Object 2 }
--     self:E( { Object1, Object2, Object3 } )
--
-- Results with the text [1]={[1]="Object",[2]=3,[3]={[1]="Object",[2]=3}} in the dcs.log.
--
--     local SpawnObject = SPAWN:New( "Plane" )
--     local GroupObject = GROUP:FindByName( "Group" )
--     self:E( { Spawn = SpawnObject, Group = GroupObject } )
--
-- Results with the text [1]={Spawn={....),Group={...}} in the dcs.log.
--
-- Below a more detailed explanation of the different method types for tracing.
--
-- ## 2.1. Tracing methods categories.
--
-- There are basically 3 types of tracing methods available:
--
--   * @{#BASE.F}: Used to trace the entrance of a function and its given parameters. An F is indicated at column 44 in the DCS.log file.
--   * @{#BASE.T}: Used to trace further logic within a function giving optional variables or parameters. A T is indicated at column 44 in the DCS.log file.
--   * @{#BASE.E}: Used to always trace information giving optional variables or parameters. An E is indicated at column 44 in the DCS.log file.
--
-- ## 2.2 Tracing levels.
--
-- There are 3 tracing levels within MOOSE.
-- These tracing levels were defined to avoid bulks of tracing to be generated by lots of objects.
--
-- As such, the F and T methods have additional variants to trace level 2 and 3 respectively:
--
--   * @{#BASE.F2}: Trace the beginning of a function and its given parameters with tracing level 2.
--   * @{#BASE.F3}: Trace the beginning of a function and its given parameters with tracing level 3.
--   * @{#BASE.T2}: Trace further logic within a function giving optional variables or parameters with tracing level 2.
--   * @{#BASE.T3}: Trace further logic within a function giving optional variables or parameters with tracing level 3.
--
-- ## 2.3. Trace activation.
--
-- Tracing can be activated in several ways:
--
--   * Switch tracing on or off through the @{#BASE.TraceOnOff}() method.
--   * Activate all tracing through the @{#BASE.TraceAll}() method.
--   * Activate only the tracing of a certain class (name) through the @{#BASE.TraceClass}() method.
--   * Activate only the tracing of a certain method of a certain class through the @{#BASE.TraceClassMethod}() method.
--   * Activate only the tracing of a certain level through the @{#BASE.TraceLevel}() method.
--
-- ## 2.4. Check if tracing is on.
--
-- The method @{#BASE.IsTrace}() will validate if tracing is activated or not.
--
-- # 3. DCS simulator Event Handling.
--
-- The BASE class provides methods to catch DCS Events. These are events that are triggered from within the DCS simulator,
-- and handled through lua scripting. MOOSE provides an encapsulation to handle these events more efficiently.
--
-- ## 3.1. Subscribe / Unsubscribe to DCS Events.
--
-- At first, the mission designer will need to **Subscribe** to a specific DCS event for the class.
-- So, when the DCS event occurs, the class will be notified of that event.
-- There are two methods which you use to subscribe to or unsubscribe from an event.
--
--   * @{#BASE.HandleEvent}(): Subscribe to a DCS Event.
--   * @{#BASE.UnHandleEvent}(): Unsubscribe from a DCS Event.
--
-- ## 3.2. Event Handling of DCS Events.
--
-- Once the class is subscribed to the event, an **Event Handling** method on the object or class needs to be written that will be called
-- when the DCS event occurs. The Event Handling method receives an @{Core.Event#EVENTDATA} structure, which contains a lot of information
-- about the event that occurred.
--
-- Find below an example of the prototype how to write an event handling function for two units:
--
--      local Tank1 = UNIT:FindByName( "Tank A" )
--      local Tank2 = UNIT:FindByName( "Tank B" )
--
--      -- Here we subscribe to the Dead events. So, if one of these tanks dies, the Tank1 or Tank2 objects will be notified.
--      Tank1:HandleEvent( EVENTS.Dead )
--      Tank2:HandleEvent( EVENTS.Dead )
--
--      --- This function is an Event Handling function that will be called when Tank1 is Dead.
--      -- @param Wrapper.Unit#UNIT self
--      -- @param Core.Event#EVENTDATA EventData
--      function Tank1:OnEventDead( EventData )
--
--        self:SmokeGreen()
--      end
--
--      --- This function is an Event Handling function that will be called when Tank2 is Dead.
--      -- @param Wrapper.Unit#UNIT self
--      -- @param Core.Event#EVENTDATA EventData
--      function Tank2:OnEventDead( EventData )
--
--        self:SmokeBlue()
--      end
--
-- See the @{Event} module for more information about event handling.
--
-- # 4. Class identification methods.
--
-- BASE provides methods to get more information of each object:
--
--   * @{#BASE.GetClassID}(): Gets the ID (number) of the object. Each object created is assigned a number, that is incremented by one.
--   * @{#BASE.GetClassName}(): Gets the name of the object, which is the name of the class the object was instantiated from.
--   * @{#BASE.GetClassNameAndID}(): Gets the name and ID of the object.
--
-- # 5. All objects derived from BASE can have "States".
--
-- A mechanism is in place in MOOSE, that allows to let the objects administer **states**.
-- States are essentially properties of objects, which are identified by a **Key** and a **Value**.
--
-- The method @{#BASE.SetState}() can be used to set a Value with a reference Key to the object.
-- To **read or retrieve** a state Value based on a Key, use the @{#BASE.GetState} method.
--
-- These two methods provide a very handy way to keep state at long lasting processes.
-- Values can be stored within the objects, and later retrieved or changed when needed.
-- There is one other important thing to note, the @{#BASE.SetState}() and @{#BASE.GetState} methods
-- receive as the **first parameter the object for which the state needs to be set**.
-- Thus, if the state is to be set for the same object as the object for which the method is used, then provide the same
-- object name to the method.
--
-- # 6. Inheritance.
--
-- The following methods are available to implement inheritance
--
--   * @{#BASE.Inherit}: Inherits from a class.
--   * @{#BASE.GetParent}: Returns the parent object from the object it is handling, or nil if there is no parent object.
