Query Optimization
Description
It would be useful to be able to ask the query planner to explain a query solution given some additional hypothetical index specification(s). This would allow a user to experiment with how a query would be planned with other indexes without needing to create those indexes.
Something like, in the shell::
find(...).explain().hypothesizing([indexSpec0, indexSpec1, ..., indexSpecn])
