C code for the Francis (implicit QR) algorithm including bulge chasing

This also aims to be a good "quick-start" example on using the ATLAS BLAS library (and indeed other compatible BLAS libraries). This author found the barrier of entry to using BLAS libaries was rather high; hopefully this code is helpful to others in this regard.
