latter is a special class whose work consists on performing the distribution of tasks.
This special class is used by the Automatic Update Task, which distributes tasks
between CPU cores and GPU, and Distribution Task, which distributes tasks
among computers.
The Input Task classes and subclasses handle user input-related issues. The
Update Task classes and subclasses are responsible for updating the loop state. The
CPU Update class should be used for tasks that run on the CPU, the GPU Update
