VectorMap<String, int> involved_nodes;
DUMPM ( involved_nodes );
StableSort ( involved_nodes.Begin(), involved_nodes.End(), lip );
DUMPM ( involved_nodes );
Stable sort does not seem copy key value pairs correctly for maps.
All Sorts, when used like this, only sort values, as begin/end here return iterators to values only (the value subvector).
I think that to do what you need, you can use [Stable]SortByValues and then StableSortByKeys.
(Perhaps we might add [Stable]SortBy[KeysAndValues|ValuesAndKeys] in future...)
