vgfSet
The PHP function vgfSet sets the value of a global variable.
The variable will exist during the current request and can be
accessed from any scope with the vgfGet function.
The framework uses vgfGet and vgfSet to store and retrieve global
variables without worrying about naming collisions with the framework.
