This patch divides the query timeline script into multiple modules for better maintainability and to help writing unit tests. The patch also improves parsing of utilization values from the query profile, as the order and name of counters may change within the profile, to ensure appropriate mappings between plotted readings, initially the profile is traversed to find the correct mapping.
