This commit removes the option to sort by order and also removes
`page.next` and `page.previous` variables. Instead, pages can be sorted
by two methods `date` and `weight`. The Tera `reverse` filter will
reverse either of those sorts, so the old `order` behavior can be
achieved by using the `reverse` filter with `weight`.
In place of the `previous`/`next` variables, this commit adds the
`page.earlier`/`page.later` variables (which are set when the page is
sorted by date) and the `page.heavier`/`page.lighter` variables (which
are set when the page is sorted by weight). These variables have the
advantage of not having confusing semantics when the `reverse` filter is
used.
* Remove www.bharatkalluri.in from EXAMPLES.md
The footer and source code at <https://www.bharatkalluri.in/> state that
the site was made with Hugo, so it should be deleted as an example of a
Gutenberg site.
I considered also removing the link to https://adrien.is/, since the
link appears to be dead. But I left it for now, since that could be a
temporary outage.
If you would like, I'd be happy to format EXAMPLES.md as a table, which
might help keep it looking clean as it gets more entries.
* Convert EXAMPLES.md to table
This is extremely minor, but the initial `netlify.toml` example confused
me a bit because I didn't realize that it was using a *netlify*
variable; I thought I needed to replace something with a variable from
my own configuration. I made a very minor edit to the docs to clarify.
* Add `index page` section to documentation
The current documentation does not describe how to create a index page.
I initially found this confusing, because I expected an index page to be
a **page** rather than a section. Thus, I tried to access the page
content with `{{ page.content }}` and was very frustrated when I could
not.
This addition clarifies that the index page is **always** a section,
even if it does not have any sub-pages. This should also help people
who intend to use Gutenberg to build stand-alone webpages, rather than
blogs.
