Select a file to upload. The files must look like:
      (
        ("Numbers" 1 2 14)
        ("Card1" 8 22 43)
        ("Card2" 1 2 3 4)
          ...
        ("Card_N" 1 2 3 4)
      )
Where "Numbers" is the list of numbers you have and
"Card_xx" is the name of the card and a list of the number it has.
Spaces and tabs don't matter but the parenthesis and quotes do.
