+ * This class provides an easy way to link commands to OI inputs.
+ *
+ * It is very easy to link a button to a command. For instance, you could
+ * link the trigger button of a joystick to a "score" command.
+ *
+ * This class represents a subclass of Trigger that is specifically aimed at
+ * buttons on an operator interface as a common use case of the more generalized
+ * Trigger objects. This is a simple wrapper around Trigger with the method names
+ * renamed to fit the Button object use.
