Hello,

I saw these slides http://www.slideshare.net/openobject/odoo-from-v7-to-v8-the-new-api

And it uses this: `from odoo import Model, fields`

But if I write like that, I get this error:

 File "/home/user/openerp80/addons/hr_dc_extend/models/hr_contract.py", line 1, in <module>
    from odoo import Model, fields
ImportError: cannot import name Model

Also I didn't see any standard Odoo module us this new Model class even though they showed how to use it in slides. Is it not implemented yet or I need to do something more?
