ElasticLogger

ElasticSearch logger implementation.

Messages are queued and written to the server when any of the following conditions are met:

• The message queue is full.
• The message to be logged has a LogLevel of critical or higher.
• A message is queued to be logged, and more time than the maxLogInterval constructor argument has passed.
• The logger is asked to log the message "Main thread exiting".

The name of the index that the logger writes messages to is determined by a function (the indexCreator constructor argument). This usually returns an index name based off of the current time.
