visitor-pattern

ibrahimyilmaz/kiel#40 added syntax to define Diff callback for whole adapter. But you still have no ability to define diff callback for register blocks separately.

There is example of how it may look like:

adapterOf<Animal> {
    register(
        layoutResource = R.layout.item_cat,
        viewHolder = ::CatHolder,
        diff = diff(
            areIt

Explore and create an example of how traverser's iterators API can be used in Kotlin.

It could be as as small as code snippet or full-fledged example application.

This task is intentionally vague to uncover any documentation issues, find this API and its variations are part of the challenge.

Thanks @abhishekganesan88 for taking a stub at this (this issue is related to #16 )
