This project will entail rebuilding the PECL extension as a minimalist driver interface atop libmongoc and libbson.

The goal is to implement as much of the user-facing API as possible in separate PHP components, which will increase maintainability and turn-around time for new high-level features. Additionally, by designing PHP components to rely upon a base driver interface, we could ensure forward compatibility with alternative base drivers (e.g. HHVM, something like mongofill).
