title: Convert collection of hash maps to a csv file
body: <p>I have the following collection of hash maps:</p>
  
  <pre><code>{a:"Completed" b:1 c:"Friday" d:4}
  {a:"Started" b:1 c:"Monday" d:4}
  {a:"In Progress" b:1 c:"Sunday" d:1}
  {a:"Completed" b:3 c:"Tuesday" d:9}
  </code></pre>
  
  <p>How can I convert this to a CSV file in clojure?</p>
  
  <p>i.e.</p>
  
  <pre><code>a,b,c,d
  Completed,1,Friday,4
  Started,1,Monday,4
  In Progress,1,Sunday,1
  Completed,3,Tuesday,9
  </code></pre>
  
  <p>Any help with this would be much appreciated.</p>
