Testing SteemBin

Please excuse the dust, just wanted to try out SteemBin. Not too bad. I'd like a way to enter a description/comment before the formatted text so I can give some context to my post. Plus I'd like to be able to add more tags. Right now I'll need to edit my post for a number of reasons including extra tags.

//I thought I'd test out SteemBin as I nice way to share code snippets via Steem. This is a Java program from one of my advent of code solutions.
