Improve the Logging Output that the Tool Produces

[gkapfham]

Right now the chasten tool does not have a sufficient amount of logging
statements inside of the source code. This means that it will be difficult for a
person who is debugging the tool to see what steps it is performing. Ultimately,
each of the key functions need at least a few additional logging statements!

During the completion of this task, please make sure to balance the number of
logging statements and the details that the logging statements provide and the
way in which logging statements can sometimes increase the complexity of the
code base and make the program's source code more difficult to understand.
