/**
 * require a consistent order of module dependencies
 *
 * Module dependencies should be sorted in a logical manner.
 * This rule provides two ways to sort modules, grouped or ungrouped.
 * In grouped mode the modules should be grouped in the order: standard modules - third party modules - custom modules.
 * The modules should be sorted alphabetically within its group.
 * A prefix can be specified to determine which prefix the custom modules have.
 * Without grouped set to `false` all dependencies combined should be sorted alphabetically.
 * ('module-dependency-order', [2, {grouped: true, prefix: "app"}])
