Subject Re: Netflix Demo for Taste

Would be easy to set up: needs a Recommender with a no-arg constructor that
contains all the setup logic. Then I think the target that builds
'grouplens.jar' should then build all the examples. Then the user could just
write in a different Recommender.

The Netflix data set is much much larger: the code has to choose to use only
about 1% of the data or else the memory requirement passes a gigabyte, which
is probably too much for a casual demo. It isn't really a recommender that
uses the whole data set, so maybe that is why I didn't set it up as a proper

There is more code in there which was bits of a more sophisticated effort
which is suitable for running in batch on a big machine - not demo friendly.

I see there is a Netflix recommender for Taste checked in.  Is there
directions some where for running it?  Something akin to the Group Lens
instructions would be pretty cool.

Seems like we could package up a JAR just like group lens, but I'm not sure
about where to put the data, etc.
