Table model built by aggregating or "summing" the columns of rows from the QueryResultModel.
QueryResultModel rows represent functions contained in specific executables.
This model groups function rows from the same executable and produces a single
row for that executable.  Columns are populated roughly:
   CountColumn is the number of functions in the group
   SignificanceColumn is the sum of the individual function significances in the group
 All the other columns are inherited from properties of the single executable used
 to define the group of functions.
   ExecutableNameMatch        name of the executable
   ExecutableCategoryMatch    a category associated with the executable    
   ExecutableDateMatch        date associated with the executable
   ArchitectureMatch          architecture
   CompilerMatch              compiler
   RepoColumn                 repository containing the executable
