This class is intended to be a root of tools (one per class) to manage persistence of objects inherited from TObj_Object It provides a mechanism to recover correctly typed objects (subtypes of TObj_Object) out of their persistent names
This is a special kind of object, it automatically registers itself in a global map when created, and the only thing it does is to create a new object of the type that it manages, by request
