Components are grouped. This theoretically helps if publishing a component library. It also helps when creating multiple instances of the same collection of components because components are allowed to have local refs. See TODO for more details.

The set of signals your system can respond to is configurable. To apply a signal, the system needs to know in what order components should be traversed.
