Error handling and testing infrastructure

[rhys-h-walker]

This PR adds new error handling to many features of the LoggingFramework, as well as creating tests to reflect the individual, errors/features.

• Allow for logging to be more fine grained with level
  • This will allow for the silencing of certain logging messages,
• Basic thread safety, synchronized block in produceLog
• Error handling for most cases
• Testing for basic console output
• Error handling in file-creation/string creation
• Handle null messages with a message when printing/writing
• Inputs are now screened in methods, errors reported
• Console only reporting is always active as a fallback for when file reporting breaks
• Added shutdown method to Logger
• Added tests for basic functionality: Check README in tests directory
• Application names should no longer break file systems. Still be careful as to what you name your app
