relocateGeneralisedNodes

protected abstract void relocateGeneralisedNodes()

Fix topology after generalisation. Moves nodes such that line ends are no longer dangling after generalisation, but end on the same lines they ended on before generalisation. This is necessary because nodes are implemented as immutable by this project.

Note that this method is possibly a misnomer: The nodes relocated are those that were previously affected by a generalisation process insofar as some of the lines that were using these nodes have been generalised. Nodes created in the generalisation process are not relocated.
