  * This post processor has two purposes:
  * 1) To make multi-edge, multi-measure data more compatible with row-based output
  * 		by collecting measures into a single data point. [ pt: [0, 1, 0, {v:msr1}, {v:msr2}, ... {v:msrN}]]
  * 2) To fill gaps in data where different measures have different numbers of missing values
  * 		By default, v2 responses simply skip cells that have no value.
  * 		Imagine Canada 17 and China 18 have no value for Cost, USA has value 22
  * 		Canada has no value of UnitCost for product trees (7) but both US and Canada have a value for Quantity
  * 		V2 RESPONSE:						EG:
  * 		[ pt: [ 16, 7, 0, { v:15 }]],		Brazil cost = 15
  * 											GAP....no cost for Canada, or China.
  * 		[ pt: [ 19, 7, 0, { v:21 }]],		Colombia cost = 21
  * 			:								etc.
  * 		[ pt: [ 22, 7, 0, { v:122 } ]],		USA cost = 122
  * 			:
  * 		[ pt: [ 17, 7, 1, { v:1000 }]],		Canada Quantity = 1000
  * 			:
  * 		[ pt: [ 22, 7, 1, { v:2000 }]]		USA Quantity = 2000
  *
  * 		AFTER POST-PROCESSING: In the end, these rows appear like this.
  * 		[ pt: [ 16, 7, 0, { v:15}, { v:500 } ]],
  * 		[ pt: [ 17, 7, 0, { v:null }, { v:1000 } ]],	//Canada Cost null, Quantity 1000
  * 		[ pt: [ 18, 7, 0, { v:null }, { v:3200 }]],		//China Cost null, Quantity 3200
  * 			:
  * 		[ pt: [ 22, 7, 0, { v:122 }, { v:2000 }]]		//USA Cost: 122, Quantity 2000
