Query DataONE's software repositories only

[lukecoy]

Met with Matt Jones after CodeMeta was over, he gave me some really good insight about a clever way I can work with DataONE to grab software using a specific field.

There's a field that's basically a list of all the resource files included in the project. We can comb a repos file list, looking at the extension, to determine if a file is code or not.

reached out to Matt for details, once I get a response this should be a piece of cake!
