very small bug in ScaledUnit.java

Steve,

ScaledUnit
{
    .
    .
    .
  Unit divideInto( DerivedUnit that )
  {
    return new ScaledUnit( 1.0/amount, (ScaledUnit)that.divide(derivedUnit));

    ** should be...
  
    return new ScaledUnit( 1.0/amount, (DerivedUnit)that.divide(derivedUnit));

  }
    .
    .
    .
}

Can you double check that this is correct? 

Thanks,

TomR
