[ttml2] Pull Request: Add Media Timing Semantics

nigelmegitt has just submitted a new pull request for 
https://github.com/w3c/ttml2:

== Add Media Timing Semantics ==
As discussed in the most recent two face to face meetings, add further
explanatory text for media timing semantics including timing diagrams.
Additionally reference ISOBMFF and MPEG DASH for example external ways
to offset media timelines.
