Local crystal playground for short code snippets
This is port of github.com/grafov/rust-playground for Crystal language. You can spin up a temporary project to play around with some Crystal code. It uses 'crystal new app', so the playground can have external deps added in the shard.yml, and it has a git repo initialized, so it isn't too hard to copy a playground into a standalone app.
