Module:
    Post Benchmark Processor

Description:
    This python script contains the definition of the Query_Statistics_Data_Object
    and the Freshness_Score_Query_Data_Object classes.

    These classes supplement the two post-benchmark processors to compute and
    output their results by encapsulting details of a query to be stored in a
    list/dictionary.
