Additional categories of changes

• A summary table of all the change counts would be useful (40 4 -> 1, 30 2 -> 1, 40 2 -> 4, ...)
• Where the identifiers are the same, some way of distinguishing changes where labels were modified or added and where labels were deleted would be useful
• The [1] after each clique set is very cool, but it would be cooler if it was [2:4,5] meaning that there are two cliques of 4 and 5 identifiers each.
• Counts of the prefixes in each section will probably be useful too.
