some inconsistencies in the enner.py file

[YeDeheng]

When i do python src/enner.py de < my_ner_file, namely i want to try out the dense embedding features, it shows: No such file or directory: './data/emb-manaal/glove_6B_300.txt'.

So, may I know what these emb-manaal and glove_6B_300.txtstuff are? Maybe you forget to git push some important files? Thanks.
