PLIP 239: Adapterise the ExtensibleIndexableObjectWrapper
=========================================================

See http://plone.org/products/plone/roadmap/239

The bulk of the code is in a new package, plone.indexer. You can read its
doctest here: 
http://dev.plone.org/plone/browser/plone.indexer/trunk/plone/indexer/README.txt

I've tried to make this test read as a manual for how to write new indexers.
In short, you do::

 @indexer(IMyType)
 def index_my_attribute(object, **kargs):
    return "some value to index"
 
 <adapter factory=".indexers.index_my_attribute" name="my_attribute" />

The changes to Products.CMFPlone are just to load plone.indexer and use it
instead of the old ExtensibleIndexableObjectWrapper.

There is one outstanding change that I'll do if and when I merge this: in
plone.app.content, we need to add a deprecated deferred-import for the
IIndexableObjectWrapper interface, which I've moved to the new plone.indexer
package.

Framework team Plone 3.3 review #1
----------------------------------

This PLIP gets my +1.

As usual, Martin delivers. Great implementation, great documentation. I did
add one sentence to the README to clarify why IIndexer adapters cannot be used
for workflow variables; it was a question I had while reviewing. No further
comments required. :-)

framework team review #2, 2009-01-28
------------------------------------

apart from two unfinished docstrings in `decorator.py` and one more typo i
found in the doctest (line 253) there's nothing to report.  this PLIP's
implementation makes an excellent addition in the spirit of the 3.x series.
+1 from me.
