title: Confusing term Interactors in Clean Architecture
body: <p>As per clean architecture, design Interactor is part which contains all business logic. The term Interactor is quite confusing to me. Interactor seems to me like interacting between two different layers like data and presenter. </p>
  
  <p>Is it the right term to use?
  Can anyone please clear the purpose of Interactor? Which pattern does it follow? 
  If Interactor is not what it seems to me then what is the design pattern for 
  layer-layer interaction?</p>
