Added documentation to new methods created to allow the timer to
pause/play
Added additional method to compensate for Spotify continuing to play
after pausing. 


Testing seems to indicate it plays for roughly 200,000,000 nanoseconds
after pressing the pause button. (200ms) -- The timer is dramatically
more accurate. You have to pause 1-2 times a second for more than 10
seconds to produce a discrepency more than 1-2 seconds in time.
