Remove aproach to data validation

[fherreazcue]

There are mentions about whether the data seems fabricated or not... it is not needed and it is distracting...
We can get rid of those comments, or even regenerate data to make it more "credible"...

Also, keep only 5 files, so that loops don't take as long to write the list of files.
Note: We could make one file name inconsistent (e.g. 05 instead of 5), so that it is not as simple?

This is largely done, right?

Yes, it was resolved in #29 I believe... but we need to still make sure it does not come up in the functions/conditionals episodes...
