Started run fragment (doesn't actually run yet)
Put the run fragment into its own activity and made it load (if not display anything useful)
Fixed exercise view dropdown selection.
Made the runfragment actually run again.
Added rudimentary ProgressWheels.
Modified the progress circle to have two differently-formatted lines.
Refactored to use a single countdown timer for increased smoothness.
Refactored the way that programs are run, running a program twice *nearly* works.
Removed remaining program node observer cruft... it wasn't helping.
Fixed re-run programs thinking that they were finished one exercise too early.
Made the service cleanup work a bit better.
Made the pause/play button change back to play on completion
Improved the way the buttons respond to the program running.
