Code Quality Improvements for parfait

[george.kankava@xxxxxxxxxxxxxx]

Hello,

I'd like to send you some pull requests to improve the maintainability of 
parfait.

My company - DevFactory - is sponsoring me to identify and fix code quality 
issues and improve unit test coverage in open source projects. DevFactory is 
obsessed with code quality and is providing its commercially available code 
quality improvement service for free to qualified open-source projects.

If you are interested, please let me know and we will add it to our pipeline. 
Our first step will be to utilize tools like PMD, FindBugs and Sonar to 
identify the most important issues to fix. Once we fix them, we'll follow up 
with some pull requests.

Thanks,
George
