fix(Graph): DAG/connected 函数中计算边数上限的错误

[weilycoder]

语句cyaron.Graph.DAG(10, 90, repeated_edges=False) 将导致无限循环。

cyaron/cyaron/graph.py

Lines 609 to 615 in 0865426

	if not repeated_edges:
	max_edge = Graph._calc_max_edge(point_count, not loop, self_loop)
	if edge_count > max_edge:
	raise Exception(
	"the number of edges of this kind of graph which has %d vertexes must be less than or equal to %d."
	% (point_count, max_edge))

应把 610 行的 not loop 换成 loop。

@Mr-Python-in-China 你直接修了吧
