Create a python module for each data science step

[fernandojunior]

For example, create modules based on each step of a CRISP-DM process:

src/
     __init__.py
     preprocess.py   # put functions you need to join, clean, transform and prepare features.
     modeling.py      # put functions you need to train the model and also perform predictions
     evaluate.py      # put functions you need to validate your model
