Pure Rust implementation of some Blas operations:
* `.iamax()` retuns the index of the maximum value of a vector.
* `.axpy(...)` computes `self = a * x + b * self`.
* `.gemv(...)` computes `self = alpha * a * x + beta * self` with a matrix and vector `a` and `x`.
* `.ger(...)` computes `self = alpha * x^t * y + beta * self` where `x` and `y` are vectors.
* `.gemm(...)` computes `self = alpha * a * b + beta * self` where `a` and `b` are matrices.
* `.gemv_symm(...)` is the same as `.gemv` except that `self` is assumed symmetric.
* `.ger_symm(...)` is the same as `.ger` except that `self` is assumed symmetric.
