Started fresh, authentication and matchmaking all simple and working
Added active run window and moved match making logic there.  I left a couple todos where I need to handle match invites properly
Removed files associated with prior commit
Condensed to a single view controller for simplicity
Scrolling logging to screen now works
Added PSLocationManager, doesn't seem to be sending movement updates, I'll investigate tomorrow on the train while I'm moving
Implemented some start/stop run logic, so button now says 'Stop' when appropriate and match is disconnected
timer now displays run time during match
Current and average pace labels are now populated
Total miles ran now displayed
Removed unused UI elements
sending/receiving data now working (on simulator as well as iphone -- I had just forgotten to set match delegate)
Miles ahead label should now be updated when either local GPS reports distance update or message received from other player about their distance changing
fixed possible bug with multiple matches and miles ahead label
Added open ears for text to speech, based off instructions at http://www.politepix.com/openears/tutorial
Work around annoying sounding blip spoken by open ears during decimal numbers
Added unit test for twoDecimalDigitStringWithoutRoundingFrom
changed a method to a function (seems much less verbose for utility functionality), and spoken/displayed distances are now truncated consistently
gps updates now continue to get sent over network while screen locked
open ears now speaks in background and while locked, and mixes (poorly) with other audio
