# Provides support for breadcrumbs, which allow the user to go up in the

module Breadcrumbs
# Creates a breadcrumb trail leading from the current item to its parent,
# to its parent’s parent, etc, until the root item is reached. This
# function does not require that each intermediate item exist; for
# example, if there is no `/foo/` item, breadcrumbs for a `/foo/bar/` item
# will contain a `nil` element.
#
# @return [Array] The breadcrumbs, starting with the root item and ending
# with the item itself
