--- SPAWNSTATIC Class
-- @type SPAWNSTATIC
-- @extends Core.Base#BASE


--- # SPAWNSTATIC class, extends @{Base#BASE}
-- 
-- The SPAWNSTATIC class allows to spawn dynamically new @{Static}s.
-- 
-- There are two modes how SPAWNSTATIC can spawn:
-- 
--   * Through creating a copy of an existing Template @{Static} as defined in the Mission Editor (ME).
--   * Through the provision of the type name of the Static.  
-- 
-- Spawned @{Static}s get **the same name** as the name of the Template Static, 
-- or gets the given name when a Static Type is used.  
-- Newly spawned @{Static}s will get the following naming structure at run-time:
-- 
--   * Spawned @{Static}s will have the name _StaticName_#_nnn_, where _StaticName_ is the name of the **Template Static**, 
--   and _nnn_ is a **counter from 0 to 99999**.
-- 
--   
-- ## SPAWNSTATIC construction methods
-- 
-- Create a new SPAWNSTATIC object with the @{#SPAWNSTATIC.NewFromStatic}() or the @{#SPAWNSTATIC.NewFromType}() methods:
-- 
--   * @{#SPAWNSTATIC.NewFromStatic}(): Creates a new SPAWNSTATIC object given a name that is used as the base of the naming of each spawned Static.
--   * @{#SPAWNSTATIC.NewFromType}(): Creates a new SPAWNSTATIC object given a type name and a name to be given when spawned.
--
-- ## SPAWNSTATIC **Init**ialization methods
-- 
-- A spawn object will behave differently based on the usage of **initialization** methods, which all start with the **Init** prefix:  
-- 
--   * @{#SPAWNSTATIC.InitRandomizePosition}(): Randomizes the position of @{Static}s that are spawned within a **radius band**, given an Outer and Inner radius, from the point that the spawn happens.
--   * @{#SPAWNSTATIC.InitRandomizeZones}(): Randomizes the spawning between a predefined list of @{Zone}s that are declared using this function. Each zone can be given a probability factor.
-- 
-- ## SPAWNSTATIC **Spawn** methods
-- 
-- Groups can be spawned at different times and methods:
-- 
--   * @{#SPAWNSTATIC.SpawnInZone}(): Spawn a new group in a @{Zone}.
--   * @{#SPAWNSTATIC.SpawnFromVec3}(): Spawn a new group from a Vec3 coordinate. (The group will can be spawned at a point in the air).
--   * @{#SPAWNSTATIC.SpawnFromVec2}(): Spawn a new group from a Vec2 coordinate. (The group will be spawned at land height ).
--   * @{#SPAWNSTATIC.SpawnFromStatic}(): Spawn a new group from a structure, taking the position of a @{Static}.
--   * @{#SPAWNSTATIC.SpawnFromUnit}(): Spawn a new group taking the position of a @{Unit}.
