# This runner is adapted from the typical exercises runner of LSINF1101/FSAB1401
# Its only use is to provide a sandbox to the user and provide in the feedback what is printed
# Structure used:
#  -One folder : src with a subdirectory containing the templates
#  -A run file
#  -A task file
# Note that beside this structure we use the global folder common containing:
#  -The compiler script
