How to subtract 2 dates and get minutes?

@basememara Thank you for using this library! date1 - date2 returns NSTimeInterval. So, you can get second, minute, hour, day, but cannot get month and year correctly because the days of one month is not constant.

How about something like this?

public extension NSTimeInterval {

    public var seconds: Int {
        return Int(self)
    }

    public var minutes: Double {
        return self / 60.0
    }

    public var hours: Double {
        return self / 3600.0
    }

    public var days: Double {
        return self / 86400.0
    }

}

This way, I can do something like this:

if (date1 - date2).hours < 4 {
  // Do something
}

@basememara It looks good! These operators also can be used but they are deprecated because they are incorrect as I said.

if date1 - date2 < 4.hours {
    // Do something
}

These are defined at here.

@basememara I'll close this issue but if you are still in trouble, I'll reopen.
