Finalized a first version of selection container located into a selection pipe component that works smoothly and doesn't give the flickering effect that appeared in the past. It seems to work well with tools that need to pick a solid or face. It also works well at detecting the face under mouse when a solid is clicked - this makes the floating toolbar populated properly and the tools from floating are completed correctly.
Ciplogic isolated the command line code by making it a container component.
Having all these refactorings and also the Boo changes Naro seems quite stable.
Will continue from now with bug fixing. Among the highest priority bugs that we'll solve these days: Shift select seems to not work properly in all situations, edge select for tools like Fillet3D not working yet, some shapes are disappearing and appearing back on scene.
