graph nodes values size have to be zero => output files have to be empty

"graph nodes values size have to be zero"
because of the condition to leave the main "while" loop in FAS.java

and then nothing add nodes in this "nodes" map.

Maybe that the graph must be copied before to be destroyed by the FAS algo ? (iam not sure ...)

(iam also wondering why do you publish that if the output must be empty ?... )

Maybe thanks for publishing that ... :)
