How to create a CCK formatter
CCK formatters are pieces of code that allow you to render a CCK field content how you want. In Drupal 6 this basicaly means a theme function.
As an example, we will build a formatter for the field type 'nodereference'.
This type of field, which is part of the standard CCK package, allows you to "reference" a node inside another.
The formatter that nodereference has by default, prints a standard link to the referenced node.
