// This is the implementation of the public Problem API. The pointer to
// implementation (PIMPL) idiom makes it possible for Ceres internal code to
// refer to the private data members without needing to exposing it to the
// world. An alternative to PIMPL is to have a factory which returns instances
// of a virtual base class; while that approach would work, it requires clients
// to always put a Problem object into a scoped pointer; this needlessly muddies
// client code for little benefit. Therefore, the PIMPL comprise was chosen.
