Yes you can do oneway streets in shooting star.
create a column "reverse_cost" then set reverse_cost = cost and then set
the cost or reverse cost to 10000 for the wrong way.
sone you call shortest_path_shooting_star(...., directed,
has_reverse_cost) and set both directed and has_reverse_cost to "true".
