[Paul-Bob]

Description

Allow to specify custom logger by writing it on avo.rb initializer:

  ## == Logger ==
  config.logger = -> {
    file_logger = ActiveSupport::Logger.new(Rails.root.join("log", "avo.log"))
 
    file_logger.datetime_format = "%Y-%m-%d %H:%M:%S"
    file_logger.formatter = proc do |severity, time, progname, msg|
      "[Avo] #{time}: #{msg}\n".tap do |i|
        puts i
      end
    end
 
    file_logger
  }
