This code is based on the book Machine Learning Bookcamp. The code from the book is in the org subdirectory in the form of Org files. The .py files are based on this code, with my changes and additions.

• Put the code from the book into a number of utility functions in general/utils.py.
• Modify prepare_X() to run additional functions to engineer new features.
• Add the functions binary_encode() and encode_age() for use in prepare_X().
