Add dummy JUnit test
Preliminary DefaultModelBuilder override ...
Add automatic generation of plexus metadata (use  mvn package  to get a jar with the generated components.xml). Add in a really simple override of DefaultModelBuilder.class, and a really simple JUnit test. All these things need improvement.
Modify ModelBuilder override to something that doesn't crash maven.

By extending the class we're overriding through plexus, we can avoid the problem of requiring a reference to it before it is loaded.
This commit should allow maven to continue normally, but with some extra messages output by our own class.
Rename JUnit test to to ModelBuilder class. Integration test still pending.
