how to put a label to the vector??

[beneo_7]

hi all

    I have read <<Creating+Vectors+from+Text>>, and the issues MAHOUT-65, 
MAHOUT-126, MAHOUT-236, i still have not found the way to labeling for the 
vector?  because there are no DocumentVector#getDocumentVector() or 
Vector#setLabelBindings(Map<String, Integer> bindings) in Mahout 4.0 which i 
checked out from SVN.

    In addition, i wonder that  i need to attach a patch to the SVN, however, 
the Mahout version is 4.0+, if i need to do this, then how?

    Thx advance

                                                                                
                                                                                
                                         beneo
