  ===================================================================
  This method was taken from Context.java in WM. This
  is how we'll probably be using it most of the time.
  I've left all the bean stuff in the introspection
  engine, so we'll come to beans when we get there.
  I'm basically just using the //*** type way
  to get a value because everything right now in
  Velcity is what WM calls a local variable.
  
  /**
       * Get the named local variable via introspection. This is 
       * an advanced-use method.
       */
     public final Object getLocal(final Object[] names) 
        throws PropertyException, ContextException
     {
        int len = names.length;
        if ((_locals == null) || (len == 0)) {
           return null;
        } else {
           Object res = get(names[0]);
           if (len == 1) {
              return res;
           } else if (res == null) {
              return null;
           } else {
              
              //***
              return PropertyOperator.getProperty(this,res,names,1);
           
           
           }
        } 
     }
