Lingering issues in mad-obtaining-historical-stock-prices.ipynb:

• is the folder/file creation suitable for the colab setting?
• are all the import command necessary or the standard preamble would work?

I just did some testing on Colab to make sure things are working. It turns out their version of pandas_datareader is out of date, so I added a cell to test for the module, and do an install, upgrade, and/or kernal restart as needed. This did require a fix, so good catch!

Alessandro ... after more testing on Google Colab, it's clear that getting the data files to persist and be accessible for the portfolio optimization notebook was getting too complex. So I've moved the download code back into the portfolio optimization notebook and will delete this one. A better solution would be to create a module to do the downloading and install that in the tools folder, but that will have to wait for some free time.

Sounds a good compromise for the time being. I'm leaving this open for future reference.
