This pull request introduces a new resource and several new systems to the example usage of the engine, expands the scheduler's functionality to allow dynamic removal of systems, and adds corresponding tests. The changes demonstrate a more realistic and flexible ECS (Entity-Component-System) workflow, including resource management, system scheduling, and dynamic system control.

Enhancements to engine example and ECS workflow:

• Refactored main.cpp to introduce a DirectorResource and multiple new components (NameComponent, WorkTimeComponent) and systems (DirectorMonitorSystem, HelloSystem, WorkHoursUpdateSystem, CloseSystem, WorkingSystem, GoodbyeSystem). The example now simulates a day at a school with entities, resources, and systems interacting in a realistic workflow.
• Demonstrated dynamic system control in main.cpp by enabling, disabling, and removing systems at runtime based on resource state, showcasing advanced scheduler usage.

Scheduler improvements:

• Added a Remove method to the AScheduler class, allowing systems to be removed from the scheduler at runtime by their function ID. [1] [2]

Testing:

• Added a new test RemoveSystem in SystemTest.cpp to verify that removing a system from the scheduler prevents it from running in subsequent cycles.
