Consider making FileDownloadTask public

[minimalviking]

I think making FileDownloadTask public would be very beneficial, it would allow extending this class for custom usage of the library

Thanks for your deep thinking.

Could you give me some cases and I will consider about it.

ps: I hide the FileDownloadTask Class because there are some internal mechanisms. (like: Let outside create tasks just only through FileDownloader. strict and safe) (and already public BaseDownloadTask, you can do almost everything you want on it.)

Oh you're right - I've just noticed that BaseDownloadTask has a setTag method:)

Yes, you got it. thanks anyway :)
