/**
* Annotation placed on classes that are to be automatically added
* to an hk2 {@link org.testifyproject.glassfish.hk2.api.ServiceLocator}. A service
* marked with this annotation has the org.testifyproject.testifyprojectfault scope of {@link javax.inject.Singleton},
* but any other scope annotation placed on the class will override that org.testifyproject.testifyprojectfault.
*
* This annotation is read at build time using the hk2-inhabitant-generator
* and information about the service is placed into a file in the
* associated jar. The usual way to get these services into
* a {@link org.testifyproject.glassfish.hk2.api.ServiceLocator} is to use a
* {@link org.testifyproject.glassfish.hk2.api.Populator} as provided by the
* {@link org.testifyproject.glassfish.hk2.api.DynamicConfigurationService#getPopulator()}
* method. An easier way to do that is with the
* {@link org.testifyproject.glassfish.hk2.utilities.ServiceLocatorUtilities#createAndPopulateServiceLocator()}
* utility.
