MAHOUT-104: update
OK, I checked in another interim that does:
1. Separates out Taste WAR and builds it. Haven't tested it yet, but
the structure looks good.
2. Creates the Hadoop JOB jar (core/target, and examples) Haven't
tested these yet
3. Deferred gpg signing to deploy. Not quite sure on this one yet,
but I don't see a need to sign when just doing an install.
Try doing "mvn install" from the top. If you want to run the example
tests, you need to make sure you do "install" in the core directory
first.
I'll continue tomorrow, but please try things out and give me feedback.

How to build it previously? http://lucene.apache.org/mahout/taste.html
but the only thing you should need is "ant build-grouplens-example",
and looking at the old build file should show what that does. It
really only calls to the war-building target with certain parameters.
That part does indeed belong more with "examples" but whatever's
easiest and reasonable will be fine.

OK, I hooked in some more capabilities here, so check it out. It
could still use some documentation on how to build the group lens
stuff, but the pieces should be in place, as I added in building the
grouplens jar to the examples build.

That just means the parameterization business hasn't been fully ported yet.
That token should be replaced with the caller-supplied name of Recommender
to use.

mvn install works fine here.
Big thanks for your work the maven migration and release cleanup, Grant.

The structure looks good, I successfully copied the resulting war into tomcat
and called the app at http://localhost:$port/$name_of_war/RecommenderServlet

mvn install works fine here.
Big thanks for your work the maven migration and release cleanup, Grant.
