Iterator examples

Chainer provides some iterators that implement typical strategies to create mini-batches by iterating over datasets. SerialIterator is the simplest one, which extract mini batches in the main thread. MultiprocessIterator is a parallelized version of SerialIterator. It maintains worker subprocesses to load the next mini-batch in parallel.
