[Zope] sql like functionality to query zcatalogs

[Andrew Veitch]

Hi Joel

> For example:
> select * from zcatalog where price > 2.5 and price < 2.75

result = Catalog(price = {'query': [2.5, 2.75],
                          'range': 'minmax'})

should do the job.

price would have to be a FieldIndex.
