COMPONENT: Switcher node
As a playout service provider, I want to switch between multiple sequences so that I can choose which sequence is output.
Input: multiple part 3 sequences; switching options. Output: a single part 3 sequence.
This differs from the Handover Node (#26) slightly. Handover Node is a specialisation of Switcher Node, where the logic for handing over is contained in the documents and the semantics are defined in the specification. A Switcher node can be instructed to switch based on other inputs, which are not defined. For the interoperability toolkit a basic switching rule is fine - I don't know what would be needed in real world implementations just yet.
This component is now part of the Handover node, since the handover includes switching between streams. Moved to R4 to coincide with the publication of the specification.
