corrected adjusted brandes
extracted the code to return edges from the dijkstra to a own method
added method to get the edges of only one shortest path
adjusted componentBetweenness method to be compatible with the new
getShortestEdges method.
This allowed to reduce the complexity. Now instead of recalculating the
whole edge list (result) with doing the dijkstra for each node each
time, the new getShortestEdges only calculates the new paths for the
newly drawn node and adds them.
changes
Added method to component helper to set SQL edges deleted status to 0
