I updated the web app example to be more representative of a real world app https://github.com/yogthos/graal-web-app-example

it now load the config from the environment, manage state using Mount, run migrations, and do JDBC queries, and use Hiccup for HTML templating

one thing I can't seem to get working is the session store though

it seems like the session key is always nil when running via graal, but haven't noticed anything in Ring session middleware implementation that immediately jumps out at me as being problematic
