/**
|
|
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.
