[ublas] ublas extendability 1

Hi.
I am using ublas with types other then built in scalars 
(like "double" or "int").
Typical jobs:
prod(matrix<double>,vector<v3d<double> >) or
triangular_solve(matrix<double>,vector<v3d<double> >).

In order to be able to do it, I have made partial 
specialization of "promote_traits" template in namespace
"boost::numeric::ublas" for my classes.
This works.
Is this technique good ? Or uBLAS intended only for built
in types ?

See attached files. Is it good to intervene to ublas
namespace, like done in file "vnd.h" at the end ? (please see the file)

Thank you.
 Dmitri.
