It's a shortcut. If the component only has one matching instance of the
interface, it automatically wires to that instance. So these lines are
effectively
StdControl = Router.StdControl;
StdControl = Estimator.StdControl;
I'd suggest reading the TinyOS tutorials and TinyOS programming manual (page
56) or the first half of TinyOS Programming (page 45). You can download both
from docs.tinyos.net.
