+/**
+    A type of timer class that can run multiple timers with different frequencies,
+    all of which share a single callback.
+
+    This class is very similar to the Timer class, but allows you run multiple
+    separate timers, where each one has a unique ID number. The methods in this
+    class are exactly equivalent to those in Timer, but with the addition of
+    this ID number.
+
+    To use it, you need to create a subclass of MultiTimer, implementing the
+    timerCallback() method. Then you can start timers with startTimer(), and
+    each time the callback is triggered, it passes in the ID of the timer that
+    caused it.
