研友wangleisxcc的程序基础上，我把初始化网络，训练网络，和网络使用三个稍微集成后的一个新函数bpnet

简单的BP神经网络集成，使用时直接调用bpnet就行-Friends wangleisxcc research process, I make the network initialization, training networks, and network integration using a little after three, a new function bpnet　simple BP neural network ensemble, use the line directly call bpnet
