This is (yet another) simple library to launch timed actions.
It's based on millis(), thus it has 1 ms resolution.
It uses polling, so no guarantee can be made about the exact time when a callback is fired. For example, if you setup the library so that it calls a function every 2ms, but this function requires 5ms to complete, then you'll have an invocation every 5ms.
For applications where non-strict timing is enough, not using interrupts avoids potential problems with global variables shared between the interrupt service routine and the main program, and doesn't consune a hardware timer.
