// Site contains all the information relevant for constructing a static
// site. The basic flow of information is as follows:
//
// 1. A list of Files is parsed and then converted into Pages.
//
// 2. Pages contain sections (based on the file they were generated from),
// aliases and slugs (included in a pages frontmatter) which are the
// various targets that will get generated. There will be canonical
// listing. The canonical path can be overruled based on a pattern.
//
// 3. Taxonomies are created via configuration and will present some aspect of
// the final page and typically a perm url.
//
// 4. All Pages are passed through a template based on their desired
// layout based on numerous different elements.
//
// 5. The entire collection of files is written to disk.
