Rand01AccTime: results for random (0,1) data -- all 4 routines,
     time and accuracy.

GenVecOpt18: results from using dataDesc = 18 which generates
     vectors to make the original Kahan method work as hard as
     possible.

GenVecOpt16: results from using dataDesc = 16 which generates
     vectors to make the simple loop method overflow and hence
     cause Kahan's method to be called.
