docs: Get the curated set of articles for a gene in the Entrez database.
  
      Search parameters for the Gene database query can be passed in as
      keyword arguments. 
  
      Parameters
      ----------
      hgnc_name : string
          The HGNC name of the gene. This is used to obtain the HGNC ID
          (using the hgnc_client module) and in turn used to obtain the Entrez
          ID associated with the gene. Entrez is then queried for that ID.
