I really simple, stupid MixIn to enable r/w of micromodels in Riak

riakmicromodels.py

class RiakModelMixIn(object): 
    """Simply define a property "key" that generates a key
based on the model's fields and you can store them in riak

Example::

   class MyModel(micromodels.Model):
      slug = micromodels.CharField()
      title = micromodels.CharField()

      @property
      def key(self):
         return self.slug
