Mark reachable objects from the Roots and Sweep the orphans to free memory.
The system creates objects in the young generation.
Golden spheres are ROOTS - they are always reachabe.
Click ROOTS to 'Mark' all reachable objects.
Objects that aren't marked are 'Garbage'.
Run SWEEP to collect garbage and free head space.
If the Heap reaches 100 objects, the system crashes (OOM)!
