function fn_PlotRecessionShades57_01(rec_dates, AxisDat)
% Recession shades. For some reasons, Matlab code will only take pairs of rec_dates when using rectangle.
% Inputs: rec_dates -- must be in pairs for rectangle to work.
% AxisDat -- example: AxisDat=axis([1976 2010 -.2 .15]);
% 1976 will automatically cut off the dates before 1976 in the following lines.
