Benchmark BLAS-1 Euclidean Norm Routines.
Compare the new hybrid version with 
original Algorithm 539 code rewritten to be more readable with compensated summation
Benchmarking only single precision routines
Benchmarking both real and complex routines
Benchmarking both execution times and accuracy
Data vector option used:  hybrid, simple loop overflow signals, all values in low range
Random sign given to each element
