almost works
had to add two nodes to zweibruecken
Merge branch 'master' of https://github.com/tbachcern/cpp.git into directed
created some improvements for the directed graph
by searching for circles that have an inverse
and deleting them
fixed some things
set createFrequency to fixed spectrum (6)
better removal of duplicate edges
uppdated the KL file so now it works
removes redundant edges also for undirected graphs
Merge pull request #15 from tbachcern/directed
