somnia v0.5.0

Added (0.5.0)

• Graph traversal in SELECT — a typed Path expression node for querying
  across edges created with RELATE (previously a drop to Raw). Build hops with
  Path::out::<E>() / inn / both (raw variants out_edge / in_edge /
  both_edge), constrain the destination with .to::<T>() / .to_table(...),
  chain multi-hop paths with .then_out::<E>() / .then_in::<E>(), filter a hop's
  edge with .where_(expr) (->(edge WHERE …)->table), append a .field("…") or
  .all() (.*) accessor, and anchor to a record with .from_record(thing) /
  .from_expr(...). A Path is a DynExpr, so it works as a SELECT projection
  (Table::project_path(path, alias), Select::with_path(path, alias) for
  SELECT *, <path> AS …) or inside a WHERE filter (with .contains(...),
  .eq_expr(...), .and(...) / .or(...)). Recursive {..} paths and .{…}
  destructuring are not yet covered.
