function showPopulationGrid(place,gridSize,sigma, saveFigures)
% Plots an image of the population grid of the input place
%
% INPUT:
%           place (String) - Name of polygon area in OpenSteetMap
%           gridSize (Integer) - Grid granularity in metres
%           sigma (Integer) - Standard deviation to use for gaussian blurring
%           saveFigures (boolean) - Optional boolean switch for saving figures
% OUTPUT:
%           Graph of population data overlaid on top of the highway graph
% EXAMPLE:
%           showPopulationGrid('London',400,0,true)
