Key Functions - 1.Function name : getComputationObj
                purpose : get instance of class present in library script.
                2.Function name : compute
                purpose : calculate change in market volume.
                input parameters : metadataQuery 
                output parameters : dataframe
Key variables - query : implicit variable
                WhizCalDynamicPeriodLib : The name of the object present in WhizCalDynamicPeriodLib.js(library script).
                                         execution scripts can call WhizCalDynamicPeriodLib scripts functions using given object.
                WhizCalMarketVolumeLib : The name of the object present in WhizCalMarketVolumeLib.js(library script).
                                         execution scripts can call WhizCalMarketVolumeLib scripts functions using given object.
//**Start of Function code"******************** WhizCalMarketVolumeChange **********************");
//name for metadata query, this helps logging and identification of query"WhizCalMarketVolumeChange_Query");

//calling the function from library script 
WhizCalDynamicPeriodLib.getComputationObj().compute(query, WhizCalMarketVolumeLib.getComputationObj());

 ** configuration to be set in Computation metric **

default_filter:In this section, we have added the filter that should be applied by default.
         In this section's dynamicArgs sub-section,
        1.we have added product hierarchy in order to remove the products from filters.
        2."operator": Here we specify which type of operation we want to perform
            "subtraction": It is aggregation operation and same as Aggregation.subtraction
        3."dim_mix_flag": true - Do not remove product filter
                                  false - Remove product filter
**The configuration below should be copied and pasted to calculate market volume change. *

      "type": "in",
      "column": "Market",
      "values": [
