Examples not working

[Huwyler]

This commit https://github.com/Ragarnoy/a121-rs/commit/a8a83fdde4af043fa025e86c17b425e0804a96d6#diff-9b9a2e8f8cde474d39cf02cb5e826a46ed22bdbb147e76988b2ff095dad8c41aR64-R72 (possibly also others) break the examples (e.g. radar::new() now returns a result<radar>, not a radar).

Apparently the nightly example is taken care of (at least for this change). Are the others to be considered obsolete, or are they already being worked on? I may also try to adapt them, once I have some experience with the crate. Could you give some hints/advice about the changes?
