[RuggeroVisintin]

Is your feature request related to a problem? Please describe.
Right now, there is no way to pause a system and any time the .update() method is called the system updates

Describe the experience you'd like
The system should update only if not paused, when paused the system should not update at all even when calling .update()

Describe alternatives you've considered
Add pause/resume methods to change the internal engine state
