+   A utility module to take some of the pain from parsing input while
+   writing text wrapper function for SICS.
+   
+   The idea is that you specify an array of function templates.
+   These function templates will contain function names and argument
+   information. This module will than parse the input against this
+   template. It will return -1 if an error occurs and provide error 
+   information.
+   
+   On success  the index of the function found  will be returned. 
+   Arguments will have been updated with their proper values.
+
+   Invoking functions ist still your job, probably in a switch statement
+   follwoing the call to the evaluation function.
+
