This class provides an easy way to link commands to inputs.
It is very easy to link a polled input to a command. For instance, you could link the trigger button of a joystick to a "score" command or an encoder reaching a particular value.
It is encouraged that teams write a subclass of Trigger if they want to have something unusual (for instance, if they want to react to the user holding a button while the robot is reading a certain sensor input). For this, they only have to write the Trigger#Get() method to get the full functionality of the Trigger class.
