The BLAS and LAPACK bindings for ublas are not complete yet but the
most important functions are available.

Recently, Joerg started adding blocked operations (which deteriorate performance
on vector-processors) so in the future we might need configuration macros to 
indicate if we're on superscalar or vector machines.

can't wait !
