    # Base tracker. All other trackers inherit from this class
    #
    # Accepts the following options:
    # * <tt>:line_type</tt> The line type that contains the duration field (determined by the category proc).
    # * <tt>:if</tt> Proc that has to return !nil for a request to be passed to the tracker.
    # * <tt>:output</tt> Direct output here (defaults to STDOUT)
    #
    # For example :if => lambda { |request| request[:duration] && request[:duration] > 1.0 }
