concurrency: Add detailed teaching notes for welcome and threads slides () 
These follow the flow of what I actually teach, which spends a
significant amount of time on the latter slide. I think it's worthwhile
to have a real flow documented in the teaching notes, both to make sure
nothing gets forgotten and to structure the experience of teaching.

Welcome to Concurrency in Rust

Rust has full support for concurrency using OS threads with mutexes and channels.

The Rust type system plays an important role in making many concurrency bugs compile time bugs. This is often referred to as fearless concurrency since you can rely on the compiler to ensure correctness at runtime.

  • Rust lets us access OS concurrency toolkit: threads, sync. primitives, etc.
  • The type system gives us safety for concurrency without any special features.
  • The same tools that help with "concurrent" access in a single thread (e.g., a called function that might mutate an argument or save references to it to read later) save us from multi-threading issues.
