示例1: tmp
/*
Sort graph vertices in topological order.
'vex_vec': record nodes with topological sort.
NOTE: current graph will be empty at function return.
If one need to keep the graph unchanged, clone graph
as a tmpgraph and operate on the tmpgraph.
e.g: GRAPH org;
And org must be unchanged,
GRAPH tmp(org);
tmp.sort_in_toplog_order(...)
