Detailed Description

The PageLayout class provides utility functions to control the global page layout of Stud.IP. This includes the page title, the included CSS style sheets and JavaScript files. It replaces the "traditional" way of manipulating the page header via special global variables (like $CURRENT_PAGE and $_include_stylesheet).

Each Stud.IP page should at least set the page title and help keyword (if a help page exists).
