Getting the Tuscany model objects for a contribution

[ant elder]

Someone was asking me about how to load a contribution and get the
Tuscany model objects for its artifacts so I've just committed a
testcase to show one way of doing that, see:

https://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/modules/domain-node/src/test/java/org/apache/tuscany/sca/impl/DeployerTestCase.java

That loads a contribution jar and then gets the composite, component
and service thats in the contribution. The main part of the code is:

        Node node = TuscanyRuntime.newInstance().createNode();
        String curi =
node.installContribution("src/test/resources/sample-helloworld.jar");
        node.validateContribution(curi);
        Contribution contribution = node.getContribution(curi);

If you wanted to run that in a separate Maven build outside of the
domain-node module build then the simplest dependency to use in a
Maven pom.xml is:

      <dependency>
         <groupId>org.apache.tuscany.sca</groupId>
         <artifactId>tuscany-base-runtime</artifactId>
         <version>2.0-SNAPSHOT</version>
      </dependency>

That seems the simplest approach to me, there are other ways such as
using the Deployer directly, does anyone want to show some code to do
that?
