Add citation / attribution info to results and csv download

[dlebauer]

Most of the data used by the calculator are available for use with attribution. Typically this means making it as easy as possible for users to identify and cite data products from which calculator output is derived.

Possible implementation

As a first step, adding a list of citations to the "About" page would meet the requirements of CC-By licenses.

It will be useful to have a list of sources provides

• on the results page, listed below the download buttons
• as machine-readable text, for example one of:
  • the CSV file, appended to the end as lines commented with # OR
  • by providing json input file for download (requires these files contain citation info)
  • a separate Bibtex (.bib) file

For netcdf files, the use and attribution information can be parsed from ncdump -h

Completion Criteria

• calculator meets requirements of data creators.
  • Minimum: all sources listed on About page
• output of calculator (results page + downloads) recognizes input data source
  • citation info for all calculator inputs presented on results page
  • citation info provided in machine-readable text files

I will create a .pdf file listing all sources. I agree that it would be nice to recognize specific output from each run, but I'd rank that as non-essential for publication. If its easy and we have time/ capacity to do it, I'd be happy to provide guidance.

I have initiated the file GHGVC_Methods_Sources.pdf, which is housed in a private repository that I've created with materials supporting GHGVC.

The file is here.

@caseyhofford, this file will be linked to by the "Methods & Sources" link at the top of the calculator.
