    /*
     * public static List<?> wrapList(List<?> list, Class cl) 
     * throw error if cl not a child of ViewObject
     * This block of code is going to be repeated a lot:
            List<VClassGroup> groups = // code to get the data
            List<VClassGroupView> vcgroups = new ArrayList<VClassGroupView>(groups.size());
            Iterator<VClassGroup> i = groups.iterator();

            }
            body.put("classGroups", vcgroups);
    Can we generalize it to a generic method of ViewObject - wrapList() ? 
    static method of ViewObject
    Params: groups, VClassGroupView (the name of the class) - but must be a child of ViewObject
    Return: List<viewObjectType>
