FindChromeStep is responsible for finding a chrome Widget used to theme the target view. If the current webapp.view is not a Widget, this step does nothing.

If a chrome is found, then the chrome widget replaces webapp.view, and the old view is stored in the stash as webapp.chromeView. It's the chrome's responsiblity to then call service on the chromeView.
