closing #6 #7 #8 #9 #10 - implemented a graph with threshold detection and different styles.
#12 preparing to add some diagnostics
#13 Made graph FPS 2 just to save the battery life
#11, #1 moved the Buffer to the SensorLoggerService instead of UI component, same for filtering logic.

Also, implemented the 'sound notification' for the shake even to occur, which is now also mounted to the data stream of accelerometer.
