num.Formatter now allows for a NegativeTemplate property to be able to output -10.20 as (10.20) for example.
Added more tests around numbers in general.
num.Percentage no longer extends num.Amount, instead it defines its own methods and provides an Amount() method that will respond with the factored percentage value, i.e. if the percentage is 16.0%, the Amount() method will provide 16.0.
