Title: DOC: clarify documentation for radius_neighbors

This follows a discussion on the mailing list.

I've updated the documentation to better reflect that multiple points can be queried at the same time, and to better describe why arrays of dtype object are returned.

There remains an inconsistency in the `radius_neighbors` function: when there are the same number of neighbors for every queried point (rare except when a single point is queried), the `'brute'` and `'kd_tree'` methods modify the type of the returned array; the `'ball_tree'` method does not.
