IFormatter.TimeSpanHumanize for TimeUnits larger than TimeUnit.Week

[Borzoo]

It throws an exception as there is no resource key defined for these units.

[MehdiK]

Correct. That's the expected behavior because you wouldn't know how many days go into a month (and the same is true for years considering the leap years).

Why do you need to call that directly though?

[Borzoo]

Considering it's a public method it should throw a more meaningful exception I think.

[MehdiK]

Good point. I don't think it should be public.

[MehdiK]

As mentioned in #275 I now think that we can't just change the access modifiers as there is a chance people are using this, and in fact I now think it's useful to have these as public. I guess what we need is to tidy up the exception if necessary.
