a simple stopwatch to measure how long something takes.

Usage

var s:StopWatch = new StopWatch("comma formatting took ");
Utils.commaFormat(123123123123123123123);
s.stop();
trace(s);

// is the same as

var s:StopWatch = new StopWatch("comma formatting took ");
Utils.commaFormat(123123123123123123123);
trace(s.stop());

// both output

comma formatting took 0.079 ms
