Load slides from external HTML files

[engnadeau]

The current demos have all the slides inside a single HTML monolith. Is there a recommended way of including slides from external HTML files? e.g., one slide per HTML file:

./
index.html
slides/
├─ slide1.html
├─ slide2.html

Alternatively, I can use jQuery (e.g., https://stackoverflow.com/a/9003363) to load HTML or have a build step that merges everything into a single file.
