The main view is a top-level placeholder for other views. This version is based on a one produced by start.vaadin.com service, but add a bit structure to it and populates main views automatically to it.

Suites as such for small apps that has no special needs for the main layout. Menu items can be configured (override caption, order, icon) using MenuItem annotation
