Dependency list is incomplete?

[rsharris]

The list of dependencies currently shown in the readme seems to be missing a few.

Trying to run the example shown in the readme, I find I need pybloomfilter. (and I'm not certain, but I think there are two packages with that name -- the one that pip installs appears to be badly broken).

Then when I get to the classifier stage, I discover I need jupyter. And snooping in the notebook file, it looks like I will also need sklearn.
