HAN's main.py suspicious reshape

[ei-grad]

IMDB dataset is tokenized by words, so after reshape in https://github.com/ShawnyXiao/TextClassification-Keras/blob/master/model/HAN/main.py#L20-L23 word-level dimension contain the whole words tokens, not chars/wordparts. Does it make sense at all? If it is used just for illustration, then maybe it worth to add a comment near it.
