FactoryNone

`FactoryNone` is a concept commonly used in programming, particularly with certain libraries that generate objects or components on demand. It acts as a placeholder or default value indicating "no factory has been provided." Essentially, when initializing a system, if `FactoryNone` is used, it means that there is no specific method or function assigned to create or manage objects in that spot. This provides a clear way to handle cases where object creation isn't needed or will be defined later, helping prevent errors and ensuring the program understands that no factory is currently active.
