Navigating authorship and contributions (from discussion with GBA)

• Amanda, Audrey, rOpenSci peer-reviewers as possible contributors; acknowledge in README and Wiki
• Mallory likely as third author
• Brooke as either author or contributor -- TBD
• NSF GRFP (and other funders) in description section (acknowledgement and disclosure)

• unconf as original spot
• acknowledgements, attribution, and/or disclaimers for and from supported companies (MW; BIOPAC) and maybe CSU. Ask them what they would like to include! Their legal teams might need to be in the loop, especially IF we use proprietary code from one of the supported companies; how does this influence the license (#48) selection?

@wendtke Currently in the DESCRIPTION there is a paragraph of disclaimer. Should it better be moved to LICENSE?

[wendtke]

I was going off a suggestion from @geanders . I am open to moving the NSF info, if appropriate.

We will also have disclaimers from MindWare and BIOPAC to include.

The Description field in DESCRIPTION seems supposed to be just a brief... well... description, and it is indexed by CRAN.
I believe the LICENSE file should be where all the fine print goes. It can look like this:

YEAR: 2019
COPYRIGHT HOLDER: Kathleen E. Wendt

Or maybe there's a better place for it, let's find out.
