Summary: ublas extendability1

Initial Comment:
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.
