[Moose-dev] Refactor, LaggeredTree

Hi I've made kind a big refactoring in Roassal-Algorithm, as I've learnt that ROContainer's attributes was there for any kind of use, now the CompactTree family uses it, there are new methods for ROElement in the package, but no more need of ROCompactTreeNode (former RONode). In the same time, I've written tests to be sure that the code still works (in fact it's the aim of tests I think). So now, there ain't crossing any more, in LaggeredTree. Tell me what kind of new layout you wish to see in Roassal, maybe you can have a look at D3 library. Or maybe I will start looking at how to increase roassal scalability. Just tell Regards Mathieu
