Extracts XData & YData for each line given a Figure.
This method could be useful where old simulation results have been saved only as figures.
Accepts a handle to the figure. The current figure is chosen if no argument is passed in.
Outputs 'data' is a cell array whose each cell corresponds to a line (first row XData; second row YData), when only a single set of axes exists on the figure.
If there are multiple sets of axes present (e.g. as with subplots), a cell array containing a cell array as above per each set of axes would be output.
