-The collection tracks the order in which the items are added and provides
-`algo.odict.pairs()` function to get them in this order.

-The ordered dictionary is a usual Lua table with a specific metatable. All the
-table operations are applicable.

 - The system is automatically started when the rmean instance is created. Manual starting is only required if it was previously stopped.
 - The module efficiently handles moving average calculations even with a large number of parallel running collectors and provides high-performance metrics collection capabilities.
