    Description

      In current ML BLAS.scala, all level-1 routines are fixed to use java implementation. But NativeBLAS(intel MKL, OpenBLAS) can bring up to 11X performance improvement based on performance test which apply direct calls against these methods. We should provide a way to allow user take advantage of NativeBLAS for level-1 routines, like also apply nativeBLAS for these methods.
