# This Resque extension changes the resque default logger to monologger
# and formats the log in json format.
# 
# Monologger supports printing logs in trap block.
# 
# Usage: 
#    require 'resque/plugins/custom_logger'
#    class ExecuteWorkflowJob
#      extend Resque::Plugins::CustomLogger
#      ...
#    end
