Tools for testing all memory layouts

[bernhardmgruber]

The titel is a bit provocative and also wrong. I have been repeatedly asked whether LLAMA can provide a tool to iterate over "all memory layouts" so a user can quickly test their algorithm on a variety of layouts in an attempt to find the best one. Such a tool could be technically provided, however there is no such thing as "all memory layouts". LLAMA offers a couple of common layouts, but even those have many parameters and many of them can be combined, leading to a combinatorial explosion of possibilities.

Still, since the topic came up several times, we could consider adding a dedicated example or section in the documentation on how to test an algorithm on a set of memory layouts.
