- (Fixed) FlxStandardFormatterDelegate would display inappropriately if the range bounds were greater than the range span.
- (Added) FlxRangeGraph, for drawing .. well, Range Graphs by providing upper and lower values for each x value.
- Refinements and improvements in the algorithms to process the data.
- Refinements to when labels are displayed in the axis tick labels
  (tyring to prevent overlap).
- Pinch is now asymetrical, meaning it now follows your fingers exactly
  rather than scaling at the exact enter. It provides a much more fluid
  and intuitive scaling experience.
- Data is now stored in a separate class that can be referenced by the
graphs.  This can be used to avoid duplicate stores of the same data.
- The ScatterPlot has been added but is not complete yet.
