Maybe write functions to set access|biblio|creators|attributes

We proposed three ways to author metadata:

1. Edit the metadata templates by hand (aka in Excel)
2. Edit with @aurielfournier 's rad Shiny apps
3. Use some R functions like set_access

We still need to write (3) I think. Ideally, the roxygen docs for each argument should give the user enough information to successfully fill the info in.

After thinking about this again, I'm not so sure this is that useful. We provide two interfaces for filling in dataspice metadata: (1) The CSV itself, which can be manipulated any way tables are and (2) the Shiny app.

What would a set_access function look like for example? It'd need to return a data.frame matching the access structure but what would the user pass in?

I'm going to push this to the next milestone.
