Explore using filename driven dynamic page generation

[rdmurphy]

Next.js has this cool method for rendering dynamic pages by adding extra info in the file. Sapper has a version of it too. Eleventy does it in its front matter but I find this incredibly confusing.

These all expect you to write some additional JS to react to that situation, but I wonder if we could either 1) come up with a solution that doesn't require that, and can determine everything directly in the file name, or 2) have our own version of front matter/pre-load JS that fills out the necessary fields.

I think the most ideal scenario would be to have the template and the instructions for the template as close as possible to each other if not in the same file.
