Duplicate of many flood fill kata, unfortunately.

Cheers

While this is in beta, just a few notes:

This is my first time publishing a Kata, and I'm relatively new to coding so there's doubtless some things I'm doing wrong - any contributions are appreciated, and any explanations on them even more so. I couldn't find a similar enough Kata on a cursory look through, but it's very possible they exist - if anyone knows of one, let me know here. Similarly, any translations into other languages or suggestions on how to change the description for them are appreciated.
