Build the working directory

To replicate the work I'm going to share, you will need to build a directory that will share the source code and the data. Follow these steps to build that directory.

1. Create a new directory for testing.
2. Download the 2001 NHTS ASCII.CSV data set.
3. Unzip the contents of that file into the testing directory. You should have four CSV files.

If you do not have Python already available on your machine, I'd recommend starting with Portable Python, I'm using Portable Python 1.1 which implement Python 2.5.4 as a portable program (try saying that 3 time fast!). Everything initially will work in this implementation.
