Subject: [PATCH] [SRADA-211]Horizontal Scroll Key short-cut    1. Changing
 from if to switch on TimeLineChartKeyListener    2. Adding 'a' and 'd' for
 Horizontal Scrolling    3. Adding 'q' and 'e' move start or end on timeline  
  4. double changeScroll = (120 / Math.pow(2, zoom_val))    - Fomula for
 Visible timeLine's width, Depending on changing of zoom_index

   # patch 1 : After change scale, update changed zoomIndex to zoom_val.
