[neelix-devel]uml for the model

[Hans F. <ha...@fu...>]

Made this with umbrello. Umbrello was pretty cool until it segfaulted
when I exported this image, before I got the chance to save my work.

This is more or less the data model that neelix does and will use. It
reflects the database schema as well. I left out the attr_accessors for
aggregations, leaving that up to the imagination via the aggregation
associations. Also note that quantity should be public just like all the
other accessors. 

You might notice I made the accessors attributes. I love how ruby blurs
the distinction between an attribute and its accessor.
