We need to use Result<> to manage error flow,
at least on the methods API. This way it will
finally feel idiomatic Rust and more concise.
Also, we can't return a non Result from main.
- rename NcResult to NcIntResult.
- new NcError & NcResult types.
- new error![] macro to reduce boilerplate.
- change return type of NcDirect methods to NcResult.
- refactor several examples to return NcResult:
direct-cursor, poc-direct & poc-kittyzapper.
- BONUS: fix test not stopping notcurses context.
- update lib doc-comment.
- fix typo in readme.
