This routine is the wrapper for lapack QR decomposition. Normally we don't call this
routine directly, but through qr_decompose().
If this routine was not compiled with lapack available, then it returns
ERROR with an appropriate error being set.
NO_ERROR on success, and ERROR on failure, with an appropriate error
message being set.
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
