Research direction
Start by locating the existing gemm integration and examining how it handles memory layout and strides. Compare that path with the BLAS syrk operation and determine how a gram-matrix call should be exposed; done means syrk support works for the described x.t().dot(x) case without computing redundant output.

Description
Hi.
Thank you guys for this awesome library.
In my application, I need to compute a gram matrix (basically, x.t().dot(x)).
Using gemm is wasteful, as the result is symmetric and the lower half is redundant, so using syrk in this case is twice as fast as gemm.
On a general note, it would be really useful if the library could also easily support calling any general BLAS / LAPACK function using appropriate idioms (like getting memory layout, strides, etc.)
