2.2.1.2)  Address Evaluation

Each part of an address is fully evaluated in turn. This means that a user who selects the 'a' category in the next example ends up having 'hello world!' being displayed in the top part of the browser:
   a -> b/d
   b -> c
   c/d/ t: hello world!
When a user selects the 'a' category, the address 'b/d' is evaluated. First, the 'b' part is evaluated. Because the 'b' category points to the 'c' category, the 'c' category is entered. Next, the 'd' part is evaluated. Because there is a 'd' subcategory of 'c,' this category is entered.

References can point to categories that in turn reference other categories (circular references are intercepted by the browser):
   category1 -> category2
   category2 -> filename.dii
