Second Screen/Meetingnotes/Telco 2015 01 30

Thanks to Mark Foltz who started drafting the algorithms section of the specification.
- Edited algorithms for availability,
- starting,
- joining a presentation session
Dominik rebased and edited on top of that,
- rewording availability/discovery,
- unifying terminology (browsing context / page, presentation, presentation display)
- adding terminology links
- fixing up xrefs (See Anssi's contribution notes)
Anssi suggested to follow the conventions that other specs use and merge the algorithms with the sections in which we define the IDLs and the actual properties and methods.
Dominik edited accordingly, start & join algorithms moved to the NavigatorPresenation API section, etc.

We need to flesh out the teardown/closing behavior https://github.com/w3c/presentation-api/issues/35
- Started discussion thread on this started by Mark https://lists.w3.org/Archives/Public/public-secondscreen/2015Jan/0012.html
  - native teardown vs. application level signal
  - avoiding orphaned presentations
We need to describe the message exchange more precisely https://github.com/w3c/presentation-api/issues/46, and we should consider whether other data types are acceptable for postMessage (Ongoing Mozilla implementation work seems to indicate they find that useful.)
We need to clarify the behavior of the presented page/receiver side, experiment with the implementations, make it consistent.
