 #   Global procedure. Read RGB category values from j1_categorys.yml and returns
 #   the category found with liquid var category
 #
 #    Usage:
 #      1)  assign the 'category' variable to a category name. If the category (name)
 #          couldn't be found, the category given with fallback is returned.
 #      2)  include the get_category_item.proc procedure
 #
 #  Example:
 #
 #  {% capture get_category_item %}themes/{{site.template.name}}/procedures/global/get_category_item.proc{% endcapture %}
 #  {% assign my_category = "md_indigo" %}
 #
 #  {% include {{get_category_item}} category=my_category %}
 #  {% assign my_category_item = _category_item %}
 #
 # -----------------------------------------------------------------------------
 # Test data:
 #  {{ liquid_var | debug }}
 #  _category_icons:  {{ item[0] }}: {{ item[1] }}
