! This file contains the compute intensive kernels for the Householder transformations.
!
! This is the small and simple version (no hand unrolling of loops etc.) but for some
! compilers this performs better than a sophisticated version with transformed and unrolled loops.
!
! It should be compiled with the highest possible optimization level.
!
! Copyright of the original code rests with the authors inside the ELPA
! consortium. The copyright of any additional modifications shall rest
! with their original authors, but shall adhere to the licensing terms
! distributed along with the original code in the file "COPYING".
