/**
 * Annotates a field or a setter method for injection of {@link GridMarshaller} resource. Grid marshaller
 * is provided to grid via {@link GridConfiguration}.
 * 
 * Marshaller can be injected into instances of following classes:
 * 

 * {@link GridComputeTask}
 * {@link GridComputeJob}
 * {@link GridSpi}
 * {@link GridLifecycleBean}
 * {@link GridUserResource @GridUserResource}
 * 
 * 
 * Here is how injection would typically happen:
 * 
 * public class MyGridJob implements GridComputeJob {
 *      ...
 *      @GridMarshallerResource
 *      private GridMarshaller marshaller;
 *      ...
 *  }
 * 
 * or
 *  * public class MyGridJob implements GridComputeJob {
 *     ...
 *     private GridMarshaller marshaller;
 *     ...
 *     @GridMarshallerResource
 *     public void setMarshaller(GridMarshaller marshaller) {
 *          this.marshaller = marshaller;
 *     }
 *     ...
 * }
 * 
 * 
 * See {@link GridConfiguration#getMarshaller()} for Grid configuration details.
