    Collection content summary.
    Counts item types based on "display_template" providing link to Browse page.

    E.G. --> {% include index/content.html %}

    E.G. --> {% include index/content.html object_field="format" others=true total=true %}

    Options:

    - "btn-color" - a bootstrap color class to theme the buttons. Can be any bootstrap template color (e.g. info, success) or outline (e.g. outline-info, outline-success), including colors created in config-theme-colors. (optional, default "outline-secondary")
    - "heading_level" = customize the level of the heading if necessary for accessibility, choose "h1", "h2", "h3", etc (optional, default "h2")
    - "object_field" = optionally change the field used to count items. Typically this is either "display_template" (default) or "format". The field should be available on the Browse page to filter! The icons assume you use something like "display_template" or "format" to select the correct icon.
    - "child-objects" = include child items in count or only parents, true or false (optional, default false)
    - "others" = display a count for items with no "display_template", true or false (optional, default false)
    - "total" = display a count for total items, true or false (optional, default false)
