A browser is a window-based version of a class list_browser.
It is implemented as a window
object that displays a single list_browser
object and resizes this object if the window is resized. A browser
delegates to its list_browser.
Many of the methods of class browser
direct methods defined for both class window
and class list_browser
to the list_browser. Inheritance is considered before delegation in
PCE's message passing algorithm.
