doesArgumentChangeMakeSense

private boolean doesArgumentChangeMakeSense(Vertex oldArgument,

 Mapping mapping)

Sometimes the diffing algorithm will give us an argument change when the argument container changed i.e. the argument was "moved" around because the deleted and newly added arguments look similar.

We only want to report argument type changes if it makes sense i.e. if the argument container was the same.

getTraversalOrder

The input list of EditOperations does not conform to any order.

We need to sort it as we sometimes rely on the parents being processed first.

e.g. we ignore a new argument if the parent of the argument is new. However, if the argument addition is processed before the
