// This function takes a ROOT TGraphErrors Object and swaps the x and y coordinates
// of the data points. This is especially useful if you want to use the TGraph/TGraphErrors built-in interpolation
// functionality. Say you have measured a calibration function to get from x values to y values. But now
// you measure new y values and want to determine the corresponding x values ...
