Does anyone know what the org.usfirst.frc.teamXXXX.robot.triggers package is used for

I recently saw that an empty package called org.usfirst.frc.team1218.robot.triggers was added to the command based robot project template and was unsure what it was used for. I couldn’t come across any information that explained its use and I was curious why it exists.
Thanks for the help.

Thank you i was wondering the same thing.

Additionally commands can be triggered by arbitrary conditions of your choosing by using the Trigger class instead of Button. Triggers (and Buttons) are usually polled every 20ms or whenever the scheduler is called.
