---++ Documentation
%STARTSECTION{"documentation"}%
This is a "getter" TopicFunction that returns a list of known TopicTypes
in a given web. Use it to create a selection in DataForms for the !TopicType formfield.
It adds the "none" type so that you can have (temporarily) un-typed topics. The 
type "TopicType" is added _hardcoded_ so that you don't have to rely on that type
being present in your web and to allow bootstrapping a type system in a web from
scratch on as you will be able to create an initial !TopicType !TopicType this way.

---+++++ Parameters
   * WEBS: list of webs to search for TopicTypes, defaults to BASEWEB 
   * EXCLUDE: expression to exclude types (optional)
   * ADDITION: types that are listed additionally (optional)
