title: Download a list of all pubmed ids by date (from-to)
body: <p>I need to automate PubMed article harvesting.
  I found only examples of downloading PubMed articles by term query and downloading a PubMed article by <a href="http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esummary.fcgi?db=pubmed&amp;id=11850928" rel="nofollow">pmid</a>. (ONE ARTICLE)
  But what I'm thinking about is to download a LIST of PubMed IDs by date (from-to), or all of them, like in the OAI.</p>
