Zope3 packages

These are some packages I've written while creating an inventory management application. I'll release the entire thing when it's done, but for now I'm only releasing the bits that have tests and are properly documented. These packages were developed to be used by zope3.3, but may work on older versions. Any feedback is much appreciated.

Package download

jz.common : This package is a dependency for some of the other packages.
jz.widgets.autocomplete : A client side autocomplete widget (using javascript ofcourse) for choices with a title tokenized vocabulary. Included is the clean version of the widget without the zope3 template cruft, so it can be used in any site.
jz.grid : This is a grid formatter based on zc.table formatter. Instead of table rows, the fields of each record are rendered in a list in a single cell.
jz.helpers : A collection of functions that didn't fit anywhere else.
jz.copypastemove : Modified versions of copypastemove classes.
jz.grouping : Group objects in a container according to various properties.
jz : All the packages i've made for zope (excluding the actuall application that uses all of them. to be released later). Most of the things in here have no good tests, and may be poorly documented, but I don't see myselft doing that in the near future.
