Traversing example in Scala, Groovy, Kotlin

[amatiushkin]

Add example of using this library API in Scala, Groovy, Kotlin as test or sample code or code snippet.

There is no required minimum, even one example from list is good to have:

• iterators using DFS/BFS pre/post order
• DFS pre-order and custom visitor
• DFS post-order and custom visitor
• BFS pre-oreder and custom visitor
• BFS post-order and custom visitor

The description is intentionally vague to test existing documentation.

Feel free to open issues against documentation and samples.

@amatiushkin Would like to pick this up. Please confirm.

One query I will look to complete listed traversals with one of Scala/Kotlin. What is completion criteria for this issue ?

I'd be willing to take this on and implement using Scala

@stong2351 thanks for signing up! Here is a dedicated issue for Scala: #19

Please add a comment and I will assign it to you.

I would like to add in Groovy. Would like to check if it's not picked up yet. @amatiushkin
