more gensim examples including an iterator (recurse directory into word2vec bag-of-words example:  ... need now to learn how-to extract info from it...) & an LSI and k-means scipy numpy gensim example adapted for my data (occasionally returns an empty slice...but when it does not silhouette coefficient is near 0.5) ... need to work with more complete html data, since Ginsberg vocab dominating LSI topics...
