=begin
This script generates an image with an overview of what files already exist and
what is yet to be mined.
This script traverses all the programs inside the "loda-programs/oeis" dir.
For every program that exist, a black pixel is plotted.
White pixels when there exist no program.
The image width is always 1000 pixels.
The image height varies depending on how many programs that have been mined.
The top-left pixel correspond to A000000.
The top-right pixel correspond to A000999.
