(Feature Request) Readme/doc/examples

Thanks for the crate.
It looks well-documented, but as a newcomer to Rust, I struggle with the syntax and semantics of the types. I try to figure out how the WrapXY types work (how do I construct and then use them, e.g. keeping a struct which holds a Wrap32 and I add numbers to it).
A hint in the README or an actual example in doc or code would be awesome.
