[PEAK] Trellis 0.7a1 release candidate

[Phillip J. Eby]

Hey gang, please let me know if the latest Trellis release snapshot 
works for you:

   http://peak.telecommunity.com/snapshots/Trellis-0.7a1-dev-r2529.tar.gz

Note that you will want to first consult the porting guide, here:

   http://peak.telecommunity.com/DevCenter/TrellisPorting

since your code will otherwise begin spewing lots and lots of 
deprecation warnings.  :)

Aside from the API cleanup, the only new feature is the "Pipe" 
datatype, which I've alluded to here previously.

The tutorial on the Wiki has *not* been changed to reflect the 
current release; please see the docs in the source release if you 
need to view current API examples, etc.

I'd really like to make 0.7a1 an official release on Monday, so if 
you are able to, please check it out and let me know if you have any 
problems with the porting guide or any of the changes.  Thanks!

(Oh, and yes, the Chandler "rearch" branch has already been updated 
to use the new API.)
