--- This module contains the POINT classes.
-- 
-- 1) @{Point#POINT_VEC3} class, extends @{Base#BASE}
-- ===============================================
-- The @{Point#POINT_VEC3} class defines a 3D point in the simulator.
-- 
-- 1.1) POINT_VEC3 constructor
-- ---------------------------
--  
-- A new POINT instance can be created with:
-- 
--  * @{#POINT_VEC3.New}(): a 3D point.
--
-- 2) @{Point#POINT_VEC2} class, extends @{Point#POINT_VEC3}
-- =========================================================
-- The @{Point#POINT_VEC2} class defines a 2D point in the simulator. The height coordinate (if needed) will be the land height + an optional added height specified.
-- 
-- 2.1) POINT_VEC2 constructor
-- ---------------------------
--  
-- A new POINT instance can be created with:
-- 
--  * @{#POINT_VEC2.New}(): a 2D point.
