	helper functions for EinsplineSetBuilder
	qmcplusplus::ompBLAS
	Implement selected batched and non-batched BLAS2 calls using OpenMP offload for different data types S/C/D/Z 1) column major like the BLAS fortran API 2) all the functions are synchronous, expected to be changed to asynchronous in the future.
