Added some advanced async stuff.

Really it doesn't have channels so the only advanced thing was the
dynamic trait part. Pinning the futures is only real hard part to
this module. The rest does show trait implementations on structs though
which was something missing from the library before.

Also, the project was turned into a library and the foundational
examples were put into a basic module.
