simple traversals are possible

Code
  graph <- graph %>% clear_selection()
  trav_in(graph)
Condition
  Error in `trav_in()`:
  ! There is no selection of nodes available.
  * any traversal requires an active selection
  * this type of traversal requires a selection of nodes
Code
  trav_out(graph)
Condition
  Error in `trav_out()`:
  ! There is no selection of nodes available.
  * Any traversal requires an active selection.
  * This type of traversal requires a selection of nodes.
Code
  trav_both(graph)
Condition
  Error in `trav_both()`:
  ! There is no selection of nodes available.
  * Any traversal requires an active selection.
  * This type of traversal requires a selection of nodes.
Code
  trav_in_node(graph)
Condition
  Error in `trav_in_node()`:
  ! The graph contains no selection of edges.

  * This type of traversal requires a selection of edges.
Code
  trav_out_node(graph)
Condition
  Error in `trav_out_node()`:
  ! The graph contains no selection of edges.
