    #
    #     GoodData.logging_on
    #
    def logging_on(level = nil)
      @logger = default_logger if logger.is_a? NilLogger

    # ### Example
    #
    #     GoodData.logging_http_on
    #
    def logging_http_on
      logging_on(Logger::DEBUG)

    # ### Example
    #
    #     GoodData.logging_off

    # is a logger to stdout on INFO level
    # For some serious logging, set the logger instance using
    # the logger= method

    #
    #     require 'logger'
    #     GoodData.logger = Logger.new(STDOUT)
    #
