    BAPSicle Server
    Next-gen audio playout server for University Radio York playout,
    based on WebStudio interface.

    MyRadio API Handler

    In an ideal world, this module gives out and is fed PlanItems.
    This means it can be swapped for a different backend in the (unlikely) event
    someone else wants to integrate BAPsicle with something else.
