an incomplete filter based on interfaces.

trunk.  I'm *almost* done with the merge; the only file not yet merged
is FileStorage.py.

        <h0> tags.

Fixed tests. They were comparing DateTimes which had been created at different 'resolutions' causing random but frequent failures on Windows.
Now comparing repr()'s of the DateTimes which gives just teh right level of precision.

Slightly better error reporting. Dunno why this test is failign on windows, it appears to be loosing thingthe 'decl' and 'doctype' events at the very least :-(

Fixed line ending problems causing test failure. Binary mode not appropriate as CVS checks otu with different line endings depending on the OS.

- fixed "nb"-type functionality
- fixed expression="" functionality
(Thanks to Christian Theune)

CVS----------------------------------------------------------------------

Added option to output to a file to workaround M$ OSes' inability to pipe the standard error stream.

Maybe the tests shouldn't use Unix-specific code then ;-)

Fixed a bug in lesson twelve. Changed the link in reportAction to correctly link back to the sightings page. This bug was reported by many people including Vinod Kurup.
