Benchmark BLAS-1 Euclidean Norm Routines.
Compare the new hybrid version with 
nrm2 routines supplied with Lapack version 3.5.0 using compensated sum to collect the sum of squares
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
