// This is a work-in-progress. Planned steps:
// 1) Move all Bundle-related data structures from JsepTransport
//    into this class.
// 2) Move all Bundle-related functions into this class.
// 3) Move remaining Bundle-related logic into this class.
//    Make data members private.
// 4) Refine interface to have comprehensible semantics.
// 5) Add unit tests.
// 6) Change the logic to do what's right.
