{% comment %}<!--
The categories_list include is a listing helper for categories.
Usage:
1) assign the 'categories_list' variable to a valid array of tags.
2) include helpers/categories_list.html.
example:
<ul>
{% assign categories_list = site.categories %}
{% include helpers/categories_list.html %}
</ul>
Notes:
Categories can be either a Hash of Category objects (hashes) or an Array of category-names (strings).
The encapsulating 'if' statement checks whether categories_list is a Hash or Array.
site.categories is a Hash while page.categories is an array.
This helper can be seen in use at: ../_layouts/default.html
