More examples

[johnfercher]

Hey, first of all. Congratulations, this package is awesome =)

Could you provide more examples? I would like to use the in operation, but I cannot find an example of how to use it.

Thank you very much!

I'm planning to continue working on this in the coming days and weeks. Adding more documentation is absolutely on top of the priority list.

In the meantime you could take a look at the test for the in operator in lib.rs, either for the usage with strings or with arrays. The tests will be moved into a dedicated directory and grouped in multiple files so they can be used as a reference.
