It looks like circular span can adapt any suitable STL container into a circular one. In fact, circular array and vector are implemented by inheriting privately from std::array and circular::span, which is nice. However, wouldn't it be more general to provide a circular_adaptor, which works with any vector or array, and perhaps even any STL container? Perhaps someone wants a circular set?

This is the source, the renderable documentation is here:

https://github.com/breese/trial.circular/blob/develop/doc/circular.adoc

The rationale is short, I would like to know why I should use this instead of boost.circular_buffer.
