Extending AQL with User Functions

AQL comes with a built-in set of functions, but it is no full-feature programming language.

To add missing functionality or to simplify queries, users may add own functions to AQL. These functions can be written in Javascript, and must be registered via an API.

In order to avoid conflicts with existing or future built-in function names, all user functions must be put into separate namespaces. Invoking a user functions is then possible by referring to the fully-qualified function name, which includes the namespace, too.
