Updated createSimulatedSpectra and createSummedSpectrum to include stats about SNR etc. Changed MM spectrum to have 0 em (Lorentz) model

Adapted plotBaselines_and_fitted_spectra.m to include also the difference spectrum between baselines

Changed getPpmVector. On my PC the changed ppm shift was already in use since July 2020

Minor visualization changes in DF_processing. lineBroadeningExchangingPeaks.m and plot_mean_std_of_spectra_DF.m

Updated the T1 values of metabolites in getRelaxationTimes

Worked on how to plot portrait figures. It is complicated. Don't scale the figure too much in the height to avoid rescaling of text.
Also try stepwise to export it and verify tiff.
Created multiple subplots for the correlation plots in plotSimulationResults

Cleaned up a bit and adapted plot_all_test_data_profit code to new Bland-Altman plots. However the code is still not clean

Made plots much nicer
