Issue with Time Signature

[Balthov60]

Hi !
For some reason you transform the denominator of time signature to it's log2 value
But when you compute the user friendly time signature you don't revert the denominator correctly, you compute pow($logDenominator, 2) instead of pow(2, $logDenominator)

// Constructor
parent::__construct(array($numerator, log($denominator, 2), $metronomePulse, $thirtySecondNotesPerQuarterNote));

// Time signature computation
public static function getTimeSignature($numerator, $logarithmicDenominator) {
	return $numerator . '/' . pow($logarithmicDenominator, 2);
}
