Output "publicationTypes" in person_article table

[paulalbert1]

For ccole, the output is:

  "reCiterArticleFeatures": [
    {
      "pmid": 23578816,
      "publicationType": {
        "publicationTypeCanonical": "Academic Article",
        "publicationTypePubMed": [
          "Evaluation Study",
          "Journal Article",
          "Research Support, U.S. Gov't, P.H.S."
        ],
        "publicationTypeScopus": {
          "publicationTypeScopusAbbreviation": "ar",
          "publicationTypeScopusLabel": "Article"
        }
      },

I would like us to include a field publicationTypes in the person_article output. In this case, the output should be

Evaluation Study|Journal Article|Research Support, U.S. Gov't, P.H.S.
