Bug with zooming in Safari

1

If you take a d3-carto map like [this one](http://lincolnmullen.com/figures/ma-gov/ma-gov-1800.html) and zoom in and out in Safari, the points drawn in an SVG layer disappear if you zoom in too much....

It would be nice to add functions `map.maxZoom()` and `map.minZoom()` to prevent users from zooming the map too far in or out.

Performance gains using readr::read_files()

readtext is great. My students will thank you. For reading in a directory of plain text files, you can get substantial time savings (roughly 30x on my machine) by using...

Database backends

1

For very large corpora, it would be good to have a database backend so things don't have to stay in memory.

Create an index of n-grams and documents containing those n-grams, with ways to remove rare (unique?) or common n-grams, and to extract pairs of matches from that index.

Implement earth mover distances as described in this paper. There is a gensim implementation. If possible, do this using the word2vec package's GloVe implementation from @dselivanov. http://jmlr.org/proceedings/papers/v37/kusnerb15.html

Rewrite the package so that it uses DTM matrices from text2vec and LSH from the LSHR package, both from @dselivanov.
