Preprocess the data from the MultiNLI corpus so it can be used by the

Compute a worddict from the train set, and transform the words in
the sentences of the corpus to their indices, as well as the labels.
Build an embedding matrix from pretrained word vectors.
The preprocessed data is saved in pickled form in some target directory.
Args:
inputdir: The path to the directory containing the NLI corpus.
embeddings_file: The path to the file containing the pretrained
word vectors that must be used to build the embedding matrix.
targetdir: The path to the directory where the preprocessed data
must be saved.
lowercase: Boolean value indicating whether to lowercase the premises

ignore_punctuation: Boolean value indicating whether to remove
punctuation from the input data. Defaults to False.
num_words: Integer value indicating the size of the vocabulary to use
for the word embeddings. If set to None, all words are kept.
Defaults to None.
stopwords: A list of words that must be ignored when preprocessing
the data. Defaults to an empty list.
bos: A string indicating the symbol to use for beginning of sentence
tokens. If set to None, bos tokens aren't used. Defaults to None.
eos: A string indicating the symbol to use for end of sentence tokens.
If set to None, eos tokens aren't used. Defaults to None.
