[ROOT] TObject::Write(), purge and keys

Hi rooters,

I would like to have the following functionality in root:

- setting a predefined number of circles to keep in root file on
TObject::Write()
- on new Write() save keys with dates older than a predefined date or
minus n days from today.

I think it is easy to introduce. Otherwise we currently have only two
options - keep all copies of an object or keep the latest one (or set by
hand TKey::Keep() and call purge).

It would also be nice to be able to recover a copy of object by date.

I understand that this functionality is partly implemented in TKey etc.
but I would like to see a direct realization in TDirectory::Purge() and
TObject::Write()

Regards,
Anton
