title: Slickgrid minWidth and maxWidth ignored
body: <p>Slickgrid seems to be ignoring the <a href="https://github.com/mleibman/SlickGrid/wiki/API-Reference" rel="nofollow">minWidth and maxWidth attributes</a>.  Am I missing something?</p>
  
  <p>Note in the following jsFiddle, one of the columns has a <em>width</em> of 300 which is honored, while the other columns have <em>minWidth</em> and <em>maxWidth</em> set to 300 without any effect.</p>
