Add enhanced support for Repeatable annotations #122
Description
Java 8s Repeatable annotations are reducing boilerplate code on user side.
But they are complicating writing of annotation processors, since you have to process both annotation marked as repeatable and its wrapper annotation.
It should be great to provide a method in AbstractAnnotationProcessor with allows getting all elements marked with either of the the two annotations.
Additionally there should be an enhancement of annotation wrappers to access all value.
