Should move this repository

[lmckenzi]

This repo is currently hosted in the HL7 organization. However, content there is supposed to be materials managed by the standards process and for which HL7 has ultimate responsibility.

Reference implementations and implementer support software generally lies in the github.com/FHIR organization. I'd like to move this repository to the FHIR organization. Nothing else would need to change. Does anyone have concerns with me doing so?

I don't have any objection to moving this repository, but some things to consider are:

1. Ownership of this repository was transferred to HL7.
2. When ownership was transferred, we were directed to set up the repository here, under the HL7 organization. Perhaps that was a mistake.

It looks to me like GitHub handles backward compatibility for links to the old location after such transfers, and that issues and collaborators transfer, so I don't expect the move to cause any technical issues.
