<DL>
<DD>This method takes a String argument defining a classifier and
 uses it to create a base Classifier.  
 
 WARNING! This method is only called when trying to craete models
 from flat files (.mlf).  This method is highly untested and 
 foreseeably will cause problems when trying to nest arguments
 within multiplte meta classifiers.  To avoid any problems we
 recommend using only XML serialization, via saving to 
 .model.xml and using only the createModel(Classifier) method
 above.
