title: figure caption centering in nbconvert?
body: <p>I have cells underneath figures in an ipython notebook that contain figure caption text. I would like them to be centre('center')-aligned. I use "&lt; center >" in the markdown, which gives exactly the appearance I'm after in the notebook. But when nb-converting to latex, the text gets shunted over to the left. </p>
  
  <p>So is there a way to get nbconvert to recognize text alignment in markdown cells when converting to latex?</p>
  
  <p>Thanks. </p>
