Cosmetic changes, refactored to get rid of circular/conflicting imports. Added Word2VecTransformer, untested.
Fixed caching in sharded_multimodal_dataset.py
Integrating word2vec into dataset2corpus processing pipeline. Added scripts for cleaning datasets (so far very crude) and profiling word2vec transformation.
Better word2vec OOV logging.
Minor edits everywhere.
