cts with names of objects that already existed always
    resulted in an error. Now, this will only happen if the factory tag of the existing object is different
    from the tag of the existing object
<pre>
    w.factory("Gaussian::g(x[-10,10],m[0],s[3])") ;
    w.factory("Chebychev::g(x[-10,10],{0,1,2})") ; // Now OK, x has identical spec, existing x will be used.
