### Go implementation of BLAS (Basic Linear Algebra Subprograms)

Any function is implemented in generic Go and if it is justified, it is

optimized for AMD64 (using SSE2 instructions).

AMD64 implementation uses MOVUPS/MOVUPD instructions if all strides equal to 1

so it run fast on Nehalem, Sandy Bridge and newer processors but relatively

slow on older processors.

Any implemented function has its own unity test and benchmark.

#### Implemented functions
