Add statistics and sonar cleanup and blacklist

* Adding in the statistics for decisions and errors.
* Cleaned up sonar issues and added code coverage.
* Sped up JUnit tests
* Fix JUnit issues with not finding application path
* Fix TestDecision not finding persistence.xml
* Fix for lingering statistics from previous runs. That
needs to be addressed at a later time.
* Changed persistence to use properties for configuration
of database rather than hard coding the persistence.xml
* Fix for Josh's comment to use else-if
* Changed to use apache Pair
* Added blacklist guard policy
