 Given that it's probably really hard to write a C++ library that's
 both portable and fast, I figured that dispatching to BLAS would give
 us an out --- if our fancy C++ stuff isn't fast enough (or just isn't
 done yet ;-) users can fall back on a local BLAS library that's
 already been tuned for their machine.

 Personally I'd love to dump BLAS; but having the ability to use it if
 necessary would probably make my thesis advisor (an unrepentant
 Fortran programmer) happier. ;-)
