Driver console output updated
Resolved merge conflicts

- driver output styling was different
- results analysis (accuracy, confusion matrix, etc.) added
comments, style, and console output changed

- added a comment describing the last section of the driver
- adjusted some spacing (because I have OCD... a bit)
- added and extra line of output. It was not requested in the
deliverable instructions, but it seems more complete and was already
calculated.
removed redundant variable

- removed the correctClassifications variable due to redundancy
(correctHam + correctSpam = correctClassification)
