var nhe = require('highcharts-exporter');
nhe.exportChart(highchartsExportRequest, function(error, exportedChartInfo){
    if(error){
        console.log('Uh oh!',error.message);
        // Can send error message back to client
    } else{
        console.log('Exported chart. Here are the deets:', exportedChartInfo);
