A number of new functions have been introduced to uBlasVector. Are these 
functions essential? The problem that I'm facing is that we use uBlas 
objects a lot to manipulate relatively small vectors and matrices, so 
performance is a consideration. Previously we accessed uBLAS functions 
directly. This issue is compounded by the fact that I haven't been able 
to figure out how to elegantly wrap number of the functions because 
uBLAS uses expression templates.

If we need the extra functions, we'll probably try to work directly with 
uBLAS (by creating a ublas_vector). ublas_vector is base class for 
uBlasVector, so can we cast it easily to a uBlasVector?
