Consider moving this project to an organization, possibly new name

First of this, this is a fantastic project. I came here looking for Hydra support, and found Über, Siren, and HAL as well. I think this project has legs as it's very powerful.

I'd like to suggest creating a top-level organization for this project. This would make it simpler to include things like example apps, which may not leverage the same dependency set as the core project. For example, a Spring Boot example would be useful, but likely isn't a good fit for inclusion in the core project.

But this leads to another suggestion: given this project's vast support for other hypermedia formats beyond JSON-LD and Hydra, is hydra-java a reasonable name going forward? This project seems to be shaping up to be a general-purpose Hypermedia framework, of which JSON-LD plus Hydra is one such option. Thoughts?
