*\brief DayZInfectedCommandScript fully scriptable command
*	\warning NON-MANAGED, will be managed by C++ once it is sent to the CommandHandler through DayZInfected.StartCommand_Script
*	\note So ideally, it is best to set up the DayZInfectedCommandScript, not create any instances and start it through DayZInfected.StartCommand_ScriptInst
*			In case an instance needs to be created, it needs manual deletion if not sent to the CommandHandler
*			But deleting it while it is in the CommandHandler will cause crashes
