This adds astro/components/ and moves the Prism.astro component into there. So to use in a project you can do:
```html
---
import Prism from 'astro/components/Prism.astro';
---
<Prism lang="html" code={`<html> ... </html>`}
```
* Add prism and skeleton www page
This adds a Prism plugin, a Prism component, and the skeleton of our www site (just for testing the Prism component at the moment).
* Remove debugging
