Traceroute Collector/ Aggregator for Scapy

One of the main reasons I picked up Scapy is for the graphs. I have never been a visual guy, so Scapy is like magic when it comes to network mapping let alone network traffic manipulation. Well, I really liked Scapy's basic graphing features, but when you have a large set of hosts to trace route, it gets annoying popping up the graphs with the black hole hosts. This gets true when the hosts paths to the target network. Another thing that I wanted is the ability to group endpoints.

It took me about a week along with other work to get everything down (note last weeks post), but I think I managed to get a basic implementation. I set it up so I can perform a number of individiual traceroute operations, and then drop them in a collector of sorts. Then when all the traceroutes are complete, then you can generate graphs with grouped endpoints and then the blackholes are ommitted. I borrowed some code from Philippe's implementation of TracerouteResult.make_graph. There is alot of extra code in TracerouteCollector class because I was tried a few different ways of forming the graph. I eventually got so frustrated that I create a basic traceroute path string and parse that result. I attempted merging TracerouteResults as well as maintaining other stuff, but it got complex quick, which lead to more frustration.
