/**
 * The Directions component provides a way to calculate directions, between two or more input locations with a [RouteLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/RouteLayer/), using ArcGIS Online and custom Network Analysis Route services.
 * This component generates a route finding a least-cost path between multiple points using the routing service associated with the assigned RouteLayer. The route is calculated based on the stops and barriers added to the RouteLayer. The component provides a user interface for adding, removing, and reordering stops and barriers. Once the route is solved, the component displays the route on the map and provides turn-by-turn directions in a list format.
 *
 * Directions uses the [Search component](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-search/) to locate each stop, either by selecting a point on the map, or by entering a search term into the textbox.
 * Search uses settings defined in the `Search properties`. This includes the `locationType`, which defines the type of geocoding result that is returned, and defaults to "street".
 *
 * Directions requires a RouteLayer to be associated with the `layer` property or using the `useDefaultRouteLayer` property. A RouteLayer can be programmatically created or derived from an external source like a portal item or webmap.
 * Please note that in order to view or interact with routing inputs and results, the RouteLayer must be added to the map. Routing service and symbology is configured in the layer, specifically the `url` and `defaultSymbols` properties respectively.
 *
 * The ArcGIS Online routing service requires authentication. If an API key is specified at the app level (see [Config#apiKey](https://developers.arcgis.com/javascript/latest/references/core/config/#Config-apiKey)) or component level (see [apiKey](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-directions/#apiKey))) then this key will accompany requests to both the routing service and geocoder/reverse-geocoder.
 * Please refer to the Search component for more information on geocoding.
 *
 * Locations on the map can be reverse geocoded and used as stops in the route. Click the button with a crosshairs icon to associate a location with a new or existing stop.  After clicking the button, click the map once. To cancel this process, press the `escape` key.
 * The resulting driving directions are automatically collapsed and can be optionally saved to a new or existing portal item. This can be achieved programically with `save` and `saveAs`. The `Clear` button calls the `reset()` method, which removes all stops, directions, and the solved route.
 *
 * Selecting the `Edit route` button allows you to add/move/remove stops, add/move/remove/reshape polyline barriers, and add/move/remove waypoints. To add a new waypoint, first hover the cursor over the route and select the desired point. Then select and drag the point to move and place the waypoint. By default the route will be automatically resolve at the completion of any editing operation. For more complex routes, it may be advantageous to disable auto-solving and solve as and when needed with the dedicated solve button. Currently, this is only supported in 2D MapViews.
 *
 * **Note:** Printing in Directions is in beta and considered experimental. The print preview dialog, in some scenarios, may not display as aniticipated.
