---------------------------------- DEMO ---------------------------------

All results found in the thesis "Séparation de sources en imagerie nucléaire"
can be reproduced with the demo files in the folder 'Demo/'. User must be
in the folder 'Demo/' in order to execute these scripts. Only results on 
the clinical renography dataset cannot be reproduced, because the dataset 
cannot be redistributed. Please visit https://www.dynamicrenalstudy.org to
download this dataset.
