双层随机网络的构建和可视化

通过er_mutilayer方法来创建：

Generate multilayer Erdos-Renyi network.

The produced multilayer network has a single aspect.

import pymnet

# 构建一个包含两个层，每个层有10个节点的ER网络
net = pymnet.models.er_multilayer(10, 2, p=0.2)

# 输出adjacency_matrix
print("adjacency_matrix: ", net.get_supra_adjacency_matrix())
