		CHANGES in trackObjs version 0.8-0
BUG FIXES
    o   Fixed faulty detection of conflicting existing objects
        when starting to track to an existing directory.

    o   Replaced environment on function that is in the active
        binding for a tracked object.  Previously, that function
        could, if constructed via track(obj <- value), have a
        copy of the tracked object in its environment, which would
        stay present taking up memory even if the object was
        flushed out of the tracking environment.

    o   Fixed bug that stopped track.stop(all=TRUE) from working
