It seems the "Yahoo! Finance" service which allowed to get csv files was disabled
in May 2017. I don't see any replacement.

The module Stock is completely broken. We could just delete it. For now, I suggest to add the #known bug tag to broken optional internet doctests.

Other motivated people could eventually open another ticket to fix the code or deprecate/delete the code.

Meanwhile, let's stop this file from creating noise when running doctests.
