lite additions to tornado.

Gust

Gust is a wrapper of tornado. It allows for a hello world such as:

from blueshed.gust import Gust, web

@web.get('/(.*)')
def get(request):
    """just a get"""
    return 'hello, world'

def main():
    """seperate construction from run"""
    Gust().run()

if __name__ == '__main__':
    main()

Similarly, you can write:

@web.ws_json_rpc('/websocket')
def add(a:float, b:float) -> float:
    """simple addition"""
    return a + b

And use a javascript websocket client to call the function:

const ws = new WebSocket("ws://localhost:8080/websocket");
ws.onopen = function () {
  ws.send(
    JSON.stringigy({
      jsonrpc: "2.0",
      id: 1,
      method: "add",
      params: { a: 2.0, b: 2.0 }, // or [2.0, 2.0]
    }),
  );
};
ws.onmessage = function (evt) {
  const pre = document.createElement("pre");
  pre.textContent = evt.data;
  document.body.appendChild(pre);
};

There are simple sample apps in src/tests.
