ADVERTENCIA: ESTA CLASE SI ELIMINA LOS ITEMS POR DEFECTO, TAMBIEN PROPAGA LOS FLAGS, ES COMO UNA EVOLUCION DE CSPECILZIAEDMANAGER, DADO QUE
NO SOLO PROPAGA LOS FLAGS SI NO QUE SE PEUDEN HACER MAS COSAS CON LOS ITEMS.

WARNING: IF THIS CLASS REMOVES THE DEFAULT ITEMS, IT ALSO PROPAGATES THE FLAGS. IT IS LIKE AN EVOLUTION OF CSPECILZIAEDMANAGER,
SINCE IT NOT ONLY PROPAGATES THE FLAGS BUT MORE THINGS CAN BE DONE WITH THE ITEMS.

Spanish:
Antes de incluir mqhs se podria poner CMANAGERBASE_STRICT_MODE, este define unicamente quitara verificacion de fuera de rango... para CheckPoitner
este siempre se debera de hacer, esto lo hago para optimizar, por que si se que un codigo no dara errores entonces, creo que hacer esos check, estan
por demas.. cuando lo programo, ahi creo qeu si es muy necesario..

English:
Before including mqhs, you could set CMANAGERBASE_STRICT_MODE. This defines that it will only remove the out-of-range check... for CheckPointer,
this should always be done. I do this for optimization purposes, because if I know a code won't produce errors, then I think doing those checks is unnecessary...
 when I program it, I think it's very necessary.
