Most of the work here was done with the cursor work, but I took the opportunity to decouple the View::ChangeStream class apart from View::Aggregation. The relationship there wasn't truly inheritance, and the existing implementation was a bit awkward.
Also, as with the cursor work, there are some CSOT specs that are heavily timing dependent, and the Ruby driver goes a bit too slow in places. I've had to bump the timeout values in the spec to accommodate the driver.
