Fixed bug for samples with missing data.  Called a now non-existent column name.
Found a bug in `get_publication`, null publication data returned a NULL values.  Now returns a list with NA for all values so that it works with other objects.
Added S3 methods to `get_publication`.  Should pull directly from datasets, downloads &cetera.  No method for sites yet.
Getting `get_publication` to the same consistency that the other major `get_*` functions have.
Changing names for objects so that they match the UML guide, and standard naming across the classes.  Minor clean-up.
Basically undoing the last commit.  I made a mistake calling things `site`, they should be named `site.data`.
