title: Import func from file in diffrent directory kotlin
body: <p>I have a file structure that looks like this - </p>
  
  <p><code>
  -- Parent Dir --
    -- Dir a --
      - main.kt
    -- Dir b --
      - app.kt
  </code>
  Let's say app.kt has a function <code>fun meaningOfLife():Int{return 42}</code> <br>
  How do I import <code>meaningOfLife</code> in main.kt</p>
