      * Given a fully qualified String package.ObjectName and String method name, this

      * used for calling the method on the object.  Note that MethodMirror is not a direct
      * reference to the actual method, and as such does not have compile time type
      * and signature checking.  You must ensure that you call the method with exactly the
      * same arguments and types that the method expects, or you will get a runtime exception.
      *
      * @param objectName Fully qualified name for an object, e.g. org.wikimedia.analytics.refinery.core.DeduplicateEventLogging
      * @param methodName Name of method in the object.  Default "apply".
