Discuss new underlying cocoapod

We've had several issues supporting PKRevealController, looking for other options providing similar functionality (even a simpler subset is fine with me).

Options I see include: https://www.cocoacontrols.com/tags/drawer

I think [ecslidingviewcontroller](https://www.cocoacontrols.com/controls/ecslidingviewcontroller-2) or [MSDynamicsDrawerViewController](https://www.cocoacontrols.com/controls/msdynamicsdrawerviewcontroller) are our best options.

Thoughts @jamonholmgren?
