C++的一个好库。。。现在很流行

vertices(g) = 0 1 2 3 4 
edges(g) = (0,1) (0,2) (0,3) (0,4) (2,0) (2,4) (3,0) (3,1) (3,4) (4,0) (4,1) 
vertex: 0
	out-edges: (0,1) (0,2) (0,3) (0,4) 
	in-edges: (2,0) (3,0) (4,0) 
	adjacent vertices: 1 2 3 4 
vertex: 1
	out-edges: 
	in-edges: (0,1) (3,1) (4,1) 
	adjacent vertices: 
vertex: 2
	out-edges: (2,0) (2,4)
