# A universal logger

Update logger module to use new DoubtfireLogger
user
```ruby
#
# A universal logger
#
module LogHelper
  class DoubtfireLogger < ActiveSupport::Logger
    @@logger = DoubtfireLogger.new

    def initialize
      # By default, nil is provided
      #
      # Arguments match:
      #   1. logdev - filename or IO object (STDOUT or STDERR)
      #   2. shift_age - number of files to keep, or age (e.g., monthly)
      #   3. shift_size - maximum log file size (only used when shift_age)
      #                   is a number
      #
      # Rails.logger initialises these as nil, so we will do the same
      super.new(nil,nil,nil)
    end

    # Override fatal and error to puts to the console
    # as well as log using Rails
    def fatal(msg)
      puts msg
      super(msg)
    end
    def error(msg)
      puts msg
      super(msg)
    end
  end
  def logger
    DoubtfireLogger.logger
  end

  # Export functions as module functions
  module_function :logger
end
