Function collect_compiled 

pub fn collect_compiled<'a, S: GraphStorage + 'a>(
    storage: &'a S,
    params: BTreeMap<String, LoraValue>,
    compiled: &'a CompiledQuery,
) -> ExecResult<Vec<Row>>

Drain a freshly opened cursor into a Vec<Row>. Convenience for callers that want the streaming entry point but a buffered result.
