Adding run method

The run() method wraps a callable with start() and end() calls and returns the result of the callable. Any arguments passed into the method after the callable will be passed to the callable.

[proposal] throw exceptions
throw exception if end() was called before start()

throw exception if getTime(), getMemoryUsage(), getMemoryPeak() was called before, start() -> end()

This will be very useful when bench async code, like ReactPHP or Amp

Change end() method to fluent method

In general you use these methods $bench->end(); echo $bench->getTime();

With fluent method you can "minify" the code echo $bench->end()->getTime();

Display sub millisecond times

The readableElapsedTime function supports a $round parameter, but this isn't passed to the ms output. If this is passed and the $format is removed it will work with sub millisecond times

public static function readableElapsedTime($microtime, $format = null, $round = 4)
{

    if (is_null($format)) {
        $format = '%.3f%s';
    }

    if ($microtime >= 1) {
        $unit = 's';
        $time = round($microtime, $round);
    } else {
        $unit = 'ms';
        $time = round($microtime*1000, $round);

       // $format = preg_replace('/(%.[\d]+f)/', '%d', $format);
    }

    return sprintf($format, $time, $unit);
}

Previously we would get results as 0ms, now they say 0.234ms

Would you consider implementing this?
