Benchmark BLAS-1 Euclidean Norm Routines.
Compare the new hybrid version with 
the original BLAS Level 1 routines published as Algorithm 539
Benchmarking only single precision routines
Benchmarking both real and complex routines
Benchmarking both execution times and accuracy
Data vector option used:  designed to cause the original Kahan algorithm most work before scaling
Random sign given to each element
