We have a basic ring buffer for dealing with concurrent message exchange. Currently
in the middle of reifying the traits, types and structs needed for the `hello.rs`
example of the simple `Hello, World!` greeter type actor.
Need to implement our own atomic ring buffer, as I want full control
over the feature set, to enable fine tuning optimization. Following that,
we have an outline of all the necessary components listed out in the
design doc, so implementation should happen relatively quickly.
Added desgin doc and goals. Got a reference implementation that kimi spat out, looks
like something from hardware/embedded guys, which is a great sign.
