add an index.html page that "just works"

• specify mapHeight and mapWidth in map.js
• refactor renderSwardley to draw in the browser, on window load

Thanks for taking time on this. I need to think about the changes. Things I am not sure about:

• map.js just has the logic of the map. Height and width are presentation details. Best to keep them somewhere else.

• renderSwardley has been written to be used in the browser, imported into server-side javascript or called from a framework like React. The draw function is implementation specific and probably belongs somewhere else.

We could keep map.js and renderSwardley.js and do everything else in a script in index.html. What do you think?

Makes sense. 👍 Thanks for the review!
