Show recommendations based on similarity to other datasets

[TristanDamron]

At DRGON v0.2.2, we have a dead-simple recommendation algorithm that shows only recommendations which match the tags provided in the request.

We can expand this using word2vec (https://www.npmjs.com/package/word2vec) to allow us to recommend datasets that are semantically similar to the tags you requested. This would be a helpful feature in the case when the tag you're searching for has few direct matches in the registry.
