@KristianKarl can you add some more information about this, maybe a example

[KristianKarl-zz]

The idea was that when using maven on the the command line, the generators could be set dynamically. Like:
maven graphwalker:test -DpathGenerator="random(edge_coverage(100) or time(100))"

The command line would override any graphwalker annotation. The challenge is perhaps how to set it for multiple models. Maybe using the models name or id? Like:
maven graphwalker:test -DpathGenerator={model: "modelName", pathGenerator: "random(edge_coverage(100) or time(100))"}

Will try to fix this soon, and refactor it a bit so that even #173 get fixed so that we can close three issues in one go =)
