(Partially) Complete V2 Documentation

Add [prepare training data] for distributed training on k8s

optimize import of seqToseq_net_v2 for book

change sumCost to sum

Complete documentation generation for v2 model configuration

word2vec v2 api

move paddle.reader.batch to paddle.batch

dataset reader for wmt14

Start doing v2 documentation

example usage:

import paddle.v2 as paddle

if __name__ == '__main__':
    dict_en, dict_fr =	paddle.dataset.wmt14.build_dict()
    train = paddle.dataset.wmt14.train(dict_en, dict_fr)
    test = paddle.dataset.wmt14.test(dict_en, dict_fr)

    total_train = 0
    for i in train():
        total_train += 1

    total_test = 0
    for i in test():
        total_test += 1

    print total_train, total_test
