    \file object_manager.h
    \brief this manager will ceep track of the objects  in the world
    
    This is specially designed to:
    - Give an interface to the world data
    - separate the world data from the world build,update,draw process
    - recycle deleted objects: specific for Projectils since there is a lot of world entity creation/deletion (and this needs a lot of time)
    - control the garbage collector

    TO ADD SUPPORT FOR A CLASS do the following steps:
    1. include the hader file : #include "class_header.h"
    2. add the class to the type enum classList {}; in class_list.h
    3. define a function void mCache( ClassName ) in class ObjectManager
