helpers.py module not in sys.path

[srappel]

helpers.py module is not accessible if it's in the "text-analysis/code" directory unless either...

1. the code directory is added to sys path e.g. sys.path.insert(0, '/content/drive/My Drive/Colab Notebooks/text-analysis/code')

2. helpers.py is moved from the code directory into the text-analysis dir.

This is an optional method used first here:

Or I guess we can just make the wksp_dir look at the code directory instead of text-analysis

wksp_dir = '/content/drive/My Drive/Colab Notebooks/text-analysis/code'
