Request to add transform function to transform new data after the model has been fit. #5

I've scoped this out and started work on it - you can track the progress here. The actual logic of the transform python implementation is a bit tricky, since it relies on a ton of scipy-matrix-specific conventions for shuttling the neighbor weights around... I've roughly ported over the algorithm and I'll just have to walk through its execution to make sure it's working as intended. |

Thanks so much for working on this :)

PR here Mind trying this out and seeing if it all works for you? |

Oh man! Awesome! I'm at a Google offsite right now but I'll try it out as
soon as I get a chance.

It would be great if this functionality existed in the javascript implementation as it does in the python implementation here: https://github.com/lmcinnes/umap/blob/master/umap/umap_.py#L1592
