title: mapping between interfaces in mapStruct
body: <p>Hi as of now i'm able to do the mapping between simple classes. Now i have to map between interfaces.
  Consider i have 2 interfaces where many classes implements these interfaces. Since i didn't get to know how to do, i have mapped to specific type of interface A. Now i need to do reverse mapping, where attributes may be in subclasses, how to do inverse mapping in this case. I tried @inheritinverseconfiguratioin tag it didn't work.<br>
  instead of reading descriptions, it will be really helpful if i get some code snippet in answer to understand</p>
