- * Annotation to specify desired framework settings.
+ * Specifies current framework settings.
*
- * This class provides junit rule facilities to build the framework accordingly
- * to the annotation. These rules also cache the previously created frameworks.
+ * Intended usage from tests is via the annotations:
+ * @SqlTestFrameworkConfig.MinTopNThreshold(33)
+ *
+ * In case of annotations used; it picks up all annotations from:
+ * * the method
+ * * its enclosing class and its parents
+ * if none contains a specific setting the default is being taken.
+ *
+ * All configurable setting should have:
+ * * an annotation with `value` with the desired type
+ * * the annotation itself should be annotated with itslef to set the
default value
+ * * a field should be added to the main config class

Review Comment:
I've introduced a set of classes/processor/etc to disperse this method to
the config options...its different for sure :)
