By default the exercise downloads and allows browsing 32 different data files.
To change with number to n (with n<=175, as this is the maximum available), you can run:


curl -O https://gitlab.cern.ch/LHCbOutreach/LHCbMasterclass/repository/archive.zip
unzip archive.zip
cd LHCbMasterclass.git 
cmake -DNB_DATA_FILES=n .
make
