Generate weblab resources for unit tests
Some of the services need a bunch of realistic (but free of use) documents and more generally WebLab Resources. Most of them have some XML resources in src/test/resources and this lead to difficulty when upgrading the service to a new version of the model.
- The project org.ow2.weblab.core.helpers.samples should be used to generate these test resources for all services
- All services should use this project in test-dependency to get test resources.
