squash

• max_edges argument was missing

• add the maxEdges parameter for leaves and neighbors endpoints

squash

maxEdges is now a Traversal parameter

squashing of commits

I fixed the unit tests that didn't work because of the default argument value of max_edges (it was None instead of 0) in graph.py

add an anti-Dos limit for edges traversed as a query parameter

fix + rebase

rebase

I'm not sure how to fix this problem. I just update the code and used "arc diff update..." etc

'max_edges' have now a default value (0 for no limit) which allow to simplify the java code

1/ So for the "filter that applies to visits that return nodes one by one" part, we are talking about: neighbors, walk, visit/nodes only?
2/ the filter is a query parameter I guess?

I have two questions to make sure I understand well :

complete the task on the right server and add tests

I thought we should group the code by endpoint type, all the "get" endpoints without arguments between them (we can consider them as default cases), as well as the "before" endpoints and the "get" endpoints with detailed arguments that were already coded. I may be wrong
