##
# Model that represents a single category. This model has the following relations:
#
# * category groups (one to one)
# * self (many to one)
#
# This model uses the following plugins:
#
# * sluggable (source: "name")
#
# When creating or saving a category the fields "name" and "slug" are required.
# The latter is only needed when saving an existing category as a slug will be
# generated whenever the field is empty. It's also important to remember
# that slugs have to be unique. For more info see the validate() method.
