ExtensionClass.

caused attributes to be missed with more than one level of inheritence.

withLengths to pass the new verifyClass tests.

  Because the "old" Interface package allowed the import of the Attribute
  class directly from the Interface package, and some packages
  (such as CMF) expect a class back from "from Interface import Attribute":

  - Renamed Attribute.py to _Attribute.py and did the necessary
    housekeeping to make sure all the other parts of the Interface
    package knows about the change.

  - Changed __init__.py to import Attribute from _Attribute

New features and changes:

  - Removed iclass.py  (it was no longer used).

  - Gave the base interface class (Interface._InterfaceClass) a __hash__
    method as ExtensionClass instances do not hash like normal
    instances, and we require that interfaces be hashable in order to
    store them as dictionary keys and whatnot in registries.

disappeared from the Interface package.  What replaces it?

Fix wider/narrower buttons on pt managment screen. Now supports both relative (css) and absolute widths.

Yanked OM browser default implementation for alpha 1, planning on a more modular implementation for alpha 2.

modifications were needed in Zope (only two files). A lot of unused
(or rarely) features were removed from the Interface package. Slightly
deeper imports are needed.

        clients from maintaing pipelined connections to the Zope server
        (Collector #412)

Allows clean implementation of ZCTextIndex's unindex_object method so that it plays better with ZCatalog's unindex behavior.

Completed Zope integration.

 - Land new pluggable index types, specialized for date values and
   date ranges, from branch.

  - Use more conventional "tests" directory to hold unit tests.

Added management interface to query words in the lexicon and in the process uncovered a BTreeItems bug, whee!

revert unintended change: a function return value of None should be marshalled as an xmlrpc boolean False

show that mapping.get(key, default) has a default value for default.

Casey, you have the baton now.

merged toby-xmlrpclib099-branch. Changed ZPublisher xmlrpc support to allow published methods to return None nested inside a data structure

and code accordingly.

Also rewrote the code to never create a new IIBucket unless one is
really needed (for example, if the input list has only one (bucket, weight)
pair, and the weight is 1, the input bucket can be returned as-is; and
this case will be common with score maps produced by an Okapi index).
