GroupingCollection Revitalized

Here goes my first blog.
Replace the GroupingCollection instance in any application with GroupingCollection1 for the best performance.

1) Both the Groupings and the Summaries are done in O(n ) where n is flat data row-count.

2) Since i wanted the Summaries to be calculated per row rather than per cell, i changed the function signature.

myFunc1(summaryObj:SummaryObject,depth:int,current:Object, dataField:String, operation:String):Number

instead of myFunc(iterator:IViewCursor, dataField:String, operation:String):Number

Here is a sample summary function DIV and a working example (view-source enabled)

My application has had significant performance improvement using GC1. Hopefully someone out there finds this useful.
