Provides logging functionality. This is a high-level picture of how logging works:

1. Shrun.IO sends logs per command based on the environment (i.e. is file logging on and/or do we log commands). If any logs are produced, they are formatted and sent directly to a queue.
2. Shrun also produces logs. These are "higher-level" e.g. success/failure status of a given command, fatal errors, etc. Shrun uses the functions here (e.g. putRegionLog) that handles deciding if a given log should be written to eitherboth of the consolefile log queues.
3. Shrun has two threads -- one for each queue -- that poll their respective queues and writes logs as they are found. These do no environment checking; any logs that make it to the queue are eventually written.
