Themes

Entry point

Currently the entry point (categorize_package) returns a list of themes, and the new API call in https://github.com/datagovuk/ckanext-dgu/pull/72 would like to return the reason for each suggestion.

Was ...

["theme1", "theme2"]

Should be more like ...

{
    themes: [("theme", reason), ("theme"), reason)]
    taxonomies: [("term", reason)]
}
