Function pnodes() collects the UUIDs of nodes in a path one after another and returns them in an array.

Arguments：

• Path <path>

Returns：

• Array of nodes UUIDs <array>

Common Usage

Example: Find 10 shortest paths within 5 steps from Card CA001 to CA002, and return arrays after combining the nodes' UUIDs in every path

n({_id == "CA001"}).e()[*:5].n({_id == "CA002"}) as paths
limit 10
return pnodes(paths)
