Got a basic logger script and replaced the existing print statements with logger calls

[JohnoRobson]

This adds a basic logger script that is autoloaded. The logging levels are as follows, from most granular to least:

1. TRACE
2. INFO
3. WARN
4. ERROR Where TRACE is intended for debugging small parts of the program, and ERROR is for large issues, such as a critical class instance not being present. The logger's printing level can be changed at any time by calling Logger.logging_level = Logger.LoggingLevel.{logging level goes here}
