The SaveNetsProc will simply save the current network to a file
which has a file name composed of the name of the network (from its
name
field) plus the current values of the epoch and, if present,
the batch counters. This can be placed in the loop_procs
or
final_procs
of the TrainProcess or the BatchProcess to
save networks during training or after training, respectively. Set the
mod parameters to get it to save at different intervals (e.g., m =
25
saves every 25 epochs if in the train loop procs).
