function fn_forerrgraph(yfore,yforel,yforeh,yacte,keyindx,rnum,cnum,q_m,ylab,forelabel,conlab)
%
% Graph annual (or calendar year) forecasts with one error band vs actual
% Import some data from "msstart.m"
%
% yfore: both actual and forecast annual growth data with dates in the first 2 columns
% in the order of year and month (or quarter).
% yforel: lower bound of the forecast.
% yforeh: high bound of the forecast.
% yacte: actual annual growth data with dates.
% keyindx: index for the variables to be graphed
% rnum: number of rows in subplot
% cnum: number of columns in subplot
% q_m: if 4 or 12, quarterly or monthly data.
% ylab: string array for the length(keyindx)-by-1 variables
% forelabel: title label for as of time of forecast
% conlab: x-axis label for what conditions imposed; e.g., conlab = 'All bar MS shocks inspl'
