	 * When an IValidator associates a target object with an IMessage,
	 * the WorkbenchReporter eventually resolves that target object
	 * with an IResource. Sometimes more than one target object resolves
	 * to the same IResource (usually the IProject, which is the default
	 * IResource when an IFile cannot be found). This method is called,
	 * by the WorkbenchReporter, so that the WorkbenchReporter can 
	 * distinguish between the IMessages which are on the same IResource, 
	 * but refer to different target objects. This is needed for the 
	 * removeAllMessages(IValidator, Object) method, so that when one
	 * target object removes all of its messages, that it doesn't remove
	 * another target object's messages.
	 *
	 * This method may return null only if object is null. Otherwise, an
	 * id which can uniquely identify a particular object must be returned.
	 * The id needs to be unique only within one particular IValidator.
