This PR serves as a discussion thread for debugging the Preintegration Covariance of the CombinedImuFactor.

Hii, I'm very interested in testing out the Preintegration+CombinedImuFactor implementation. Are the fixes and updated docs ready to be merged? I can provide some feedback afterwards, thanks!

We're waiting on #882 after which this should be ready to go.

@lucacarlone I had forgotten I had added a bunch of unit tests here for exactly what you were asking for in #882.

@lucacarlone whenever you get a chance, I'd love to get a review from you on this (especially since you are most familiar with the changes). I'd like to land this and #874 as soon as possible. 🙂

#874 is super easy to review. Only the CombindImuFactor.cpp file needs to be reviewed.

@varunagrawal I should be able to get to this by Wednesday (and hopefully before then)
