[BlueBream] Attribute Annotation

[Justin Ryan]

Thanks for your assistance, Adam!

I got this working today, and factored out the geolocation code to a package:

  http://launchpad.net/meteor.app.maps

I will provide a usage example soon, basically a content type needs to
alsoProvide (zcml implements seems to do the trick) my IGeoLocation,
as well as passing it to zope.formlib form.Fields() along with the
main schema.

It won't work with any schema that has an 'address' attr, perhaps some
guidance could help me to soften this design so the entire thing is an
annotation.

Latitude and Longitude are stored on IGeoCodedLocation annotation, all
seems to work, kml serves for my site.

Thanks, again!  Note below about what I did..

This seems to work, I did:

anno_factory = factory(GeoCodedLocation)

where 'factory' is imported from zope.annotation as above..
