function makeMapFromArray(plotOutputData,toPlotArray)
%makes a region-labelled plot of the variable of one's choice.  
%Inputs:
%   plotOutputData -> output data structure from makeOutputPlots.m
%   toPlotArray -> N x 1 or numRegions x 1 array containing region
%                  colorings.  If an N x 1 array is inputted, the mean
%                  value within region is used
