Add `rapid-response` tag for better discoverability

[tdooner]

Hello Healthcare Rollcall team!

I'm Tom, an engineer at Code for America and part of the team of Brigade Network members working to index projects in a way that improves discoverability of projects that are aligned with the Priority Action Areas of the network.

Since this project is featured in the Rapid Response Priority Action Area, we'd love to have it indexed in this effort as well. You can accomplish this by adding this additional tag to this repository:

• rapid-response

It looks like you already have a bunch of tags, but still you may want to consider adding other tags as well, to represent technologies in use, the format of the project, or any other affiliations. Here is a great example of a repository tagged for increased discoverability.

One more thing! While you're updating the repository, you may want to check that the repo's description and web URL are up-to-date. We will use those fields to send interested people to the right place.

Thanks! Let me know if you have any questions about this!
