If you've never had to do this, let us assure you - it isn't much fun, especially when you have ...

For those who may be wondering about the origins of the project's name, a fellow engineer in Dublin suggested this word from his native Turkish, as Uzaygezen means "space wanderer." The library supports mapping from a multi-dimensional space into one dimension via the Compact Hilbert Index. ...
