Great effort. I've left a few comments. Overall, this looks great, just needs some tweaks, namely in the tests and docs.
docs/generated/sparse.COO.rst needs the function names added in order to generate the docs.
You will need to generate the docs once in order to produce docs/generated/sparse.COO.all.rst and docs/generated/sparse.COO.any.rst and add those to git. See the section on adding docs in the CONTRIBUTING.

Should ideally be a boolean array that's sometimes false and sometimes true.

Same here. Ideally use this array for both to show the output, it's like a truth table:
x = np.array([
[False, False],
[False, True],
[True, False],
[False, False]
])(It could be formatted better)

We'll need separate tests, input should be np.bool_ arrays. Take a look at how we've produced random arrays for binary ops and use that.

Oh. Apparently you're using an old NumPy version... The docstrings need to be produced with newer versions to pass the tests, unfortunately. (1.14.0 or newer I think). |

@stsievert Are you still interested in working on this? If not, is it okay if I pushed to your branch? You'd still be listed as the author of the commit. |

It seems like NumPy 1.15 changed the docstrings for bool arrays, omitting the dtype. For the tests to pass both locally and in Travis, I needed to skip these doctests. |
