[PEAK] Trellis API in SVN

[Phillip J. Eby]

The docs are non-existent, but my example emails from the last week 
or so should provide general guidance.  In fact, I would go so far as 
to say NOT to read the documentation yet (especially not the README, 
after the first few sections), in order not to get confused!

Note that Time, IO, Signals, and timestamps aren't available yet, 
just the raw cells core.  To install, use:

    easy_install svn://svn.eby-sarna.com/svnroot/DecoratorTools
    easy_install svn://svn.eby-sarna.com/svnroot/ObjectRoles
    easy_install svn://svn.eby-sarna.com/svnroot/Contextual
    easy_install svn://svn.eby-sarna.com/svnroot/Trellis

This is necessary because I ended up needing to modify DecoratorTools 
and ObjectRoles in order to adequately support the new Trellis 
API.  (And Contextual doesn't have a Cheeseshop release yet.)

Contextual isn't actually used by the Trellis yet, except to import 
an exception class and a utility function.  But this will change as 
the various services get added (like Time, IO, and Signals).

If you want to do source checkouts instead of installing eggs, you 
can simply check out the svn URLs directly, and use "setup.py 
develop" to install them in develop mode.

Please let me know if you have any questions or discover any bugs.  I 
expect to begin work next week on some actual documentation and 
re-organized tests, followed by support for timestamps, and various 
time/task services.
