// This program takes in a trained network and an input blob, and then dumps
// all the intermediate blobs produced by the net to individual binary
// files stored in protobuffer binary formats.
// Usage:
// dump_network input_net_param trained_net_param
// input_blob output_prefix 0/1
// if input_net_param is 'none', we will directly load the network from
// trained_net_param. If the last argv is 1, we will do a forward-backward pass
// before dumping everyting, and also dump the who network.
